Some of it is culture-dependent though. The absolutely positive, primitive roots of unity only gets a sly wink in Australia, I believe.

Try Cantorâs theory of transfinite ordinals. It can blow your mind.

A joke from the site I linked myself above:
To the person who invented the number zero:
Thanks for nothing!

Ugh, that linked website has some funny jokes on it, but whoever thought it a good idea to only show half of each joke an to require clicking a button for every joke that isnât a one liner deserves to be slapped with a fish.
Anyways, another naughty sounding bit of maths:
The Coch curve, Coch snowflake, and Coch snowcube. They may look innocent, but thatâs a German-style ch, so it sounds rather naughty when spoken. ANd in case you donât know, they are a trio of related fractals. The Coch curve starts with a line segment, you replace the middle third with two sides of an equilateral triangle, and with each iteration, you perform this replacement on the middle third of every segment. The Coch snowflake starts with an equilateral triangle and does the same thing, being basically three copies of the curve combined(also, the first iteration of the snowflake is the perimeter of a hexagram). For the snowcube, you start with a regular tetrahedron(the shape of a d4 for anyone into polyhedral dice without knowing the names of shapes), and you add a smaller tetrahedron to the middle of each face, the first iteration being the stella octangula. Itâs called a snow cube because itâs both the 3-d analog of the snowflake and because it approaches the shape of a cube⊠and for the mind bendy warning, the Coch Snowflake has infinite perimeter but finite area, and the Coch Snowcube has infinite surface area, but finite volume⊠Though thatâs nothing compared to the Sierpinski Carpet and Menger Sponge, which have infinite perimeter and surface area, but zero area and volume.
Also, 1218839 is SEXY⊠and so is 1325734.

Did you know that Ï and -1 just broke up? They figured out that their relationship was not real.

I feel sorry for i and e. They thought they had a thing going but they must have imagined it.

Iâm reminded of an old* YouTube video I once watched about a date between pi and e⊠which included a joke about e not being sure sheâs normal. Also, I think there was a joke about pi making a premature love confession only to cover it up by turning I love you into I love Euclidean geometry. Also, if memory serves, their waiter was one of those constants that has itâs own symbol(I think it was either a lowercase Gamma or that funny B looking thing from the German alphabet), but which no one ever talks about.
*As in so old I literally watched it and didnât just listen to it, and my vision started failing around July 2012, so it was at least 12 years ago.

Thatâs likely Eulerâs constant Îł, which shows up a lot in analytic number theory and discrete maths. It has the honour of being the most important constant that we donât know whether it is irrational or not, to say nothing of normal.
On-topic: Iâm amazed nobody has yet mentioned the Wiener measure.

e, i, and Ï had a relationship, but it was a negative one.
[bonus points for the first person to come up with the answer to that one

Huh, I knew proving things transcendental was hard and proving things normal was nearly impossible with known math(are there any proven normal numbers other than the constant that is constructed as the concatenation of the natural numbers?) despite almost all real numbers being both transcendental and normal, but I thought irrationality proofs where on the fairly easy end of the dificulty spectrum⊠Then again, the periods of prime reciprocals grow roughly linearly with the magnitude of the prime, and I imagine finding a pair of large primes from their ratio isnât much, if any, easier than finding a pair of large primes from their product, and if the period is millions of digits, finding where the first repeat starts could be difficult, and the first million digits could repeat for a million cycles before devolving into the non-repeating, non-terminating chaos(and my apologies to any Chaos theorists reading this for the colloquial usage of this word) of irrationality⊠It being called Eulerâs constant when e is sometimes called Eulerâs number isnât confusing though.
Oh yeah, the value of the fifth busy beaver number was recently proven after being found 30 or so years ago⊠And one of the non-halting turing machines that stood in the way of Busy Beaver 5 claiming its crown takes billions of steps for any well-behaved pattern to emerge. And the actual 5 state Busy Beaver takes over 47 million steps to halt.
Also, Iâm just guessing from plugging in a few values, but does the graph of r = the zth root of z superimposed with a hyperboloid of one sheet with axis on the z-axis look as suggestive as Iâm imagining? As an aside, the girthiest part of r = the zth root of z is at z = e.
And feel free to ask if you need explanations to anything Iâve posted in this thread.

That perception has probably been contaminated by the proofs of irrationality of numbers like â2 or log 2. Proving e or Ï irrational is harder, so much that they werenât done until the 18th century (by Euler and Lambert, respectively). Other limits of âeasyâ sequences such as ζ(3) resisted efforts until 1978 (by ApĂ©ry). But proving ζ(5) irrational cannot be done by the same technique, nor the other odd integer values of the zeta function (the even integer values are long known to be irrational and expressible in terms of other constants).
Proving Îł irrational is probably much harder that that, and there are other constants that are intractable. Just try to prove that the integral of sin(sin x) between 0 and Ï is irrational. We donât even know if e+Ï is irrational!
Results such as Schanuelâs Conjecture might help, but nobody knows how to prove that eitherâŠ
Mathematicians donât normally call e âEulerâs numberâ in a professional context. Thatâs more of a pop name. If we have to refer to it in a roundabout way, we say âthe base of natural logarithmsâ. When a disambiguation is necessary with a non-technical audience, Îł is sometimes called âEuler-Mascheroni constantâ, but it is a bit of a mouthfulâŠ
But it does scan to âGary, Indianaâ opening up fabulous filking opportunities!

Not quite a joke, but a limerick:
[ (12 + 144 + 20 + 3â4) / 7 ] + 5*11 = 9ÂČ + 0
how to read it
A dozen, a gross, and a score
Plus three times the square root of four
Divided by seven
Plus five times eleven
Is nine squared and not a bit more.
Two more (from the link given above somewhere):

The first one orders one beer. The second one half of a beer. The next a quarter, the next one eighth, and so onâŠ
The barkeeper is very annoyed and gives all of them together two beer.
part 2 (political but kinda funny because of its absurdity)
An infinite number of mathematicians walk into a bar
The first mathematician orders a beer
The second orders half a beer
âI donât serve half-beersâ the bartender replies
âExcuse me?â Asks mathematician #2
âWhat kind of bar serves half-beers?â The bartender remarks. âThatâs ridiculous.â
âOh câmonâ says mathematician #1 âdo you know how hard it is to collect an infinite number of us? Just play alongâ
âThere are very strict laws on how I can serve drinks. I couldnât serve you half a beer even if I wanted to.â
âBut thatâs not a problemâ mathematician #3 chimes in âat the end of the joke you serve us a whole number of beers. You see, when you take the sum of a continuously halving function-â
âI know how limits workâ interjects the bartender âOh, alright then. I didnât want to assume a bartender would be familiar with such advanced mathematicsâ
âAre you kidding me?â The bartender replies, âyou learn limits in like, 9th grade! What kind of mathematician thinks limits are advanced mathematics?â
âHEâS ON TO USâ mathematician #1 screeches
Simultaneously, every mathematician opens their mouth and out pours a cloud of multicolored mosquitoes. Each mathematician is bellowing insects of a different shade. The mosquitoes form into a singular, polychromatic swarm. âFOOLSâ it booms in unison, âI WILL INFECT EVERY BEING ON THIS PATHETIC PLANET WITH MALARIAâ
The bartender stands fearless against the technicolor hoard. âBut waitâ he inturrupts, thinking fast, âif you do that, politicians will use the catastrophe as an excuse to implement free healthcare. Think of how much that will hurt the taxpayers!â
The mosquitoes fall silent for a brief moment. âMy God, youâre right. We didnât think about the economy! Very well, we will not attack this dimension. FOR THE TAXPAYERS!â and with that, they vanish.
A nearby barfly stumbles over to the bartender. âHow did you know that that would work?â
âItâs simple reallyâ the bartender says. âI saw that the vectors formed a gradient, and therefore must be conservative.â
