Those who understand ternary, those who don’t, and those who thought this was a binary joke.
(Stolen from someone’s signature in another forum. )
There are 10 types of people: 1 who understands hex and F all the other types.

A: Because OCT 31 = DEC 25
The most esoteric joke I ever made was one time when I happened to be standing among four co-workers who were all quite tall. I said I felt like I was in a Yasujiro Ozu movie.
And, no, nobody got it.
Ozu was known for shooting scenes from a very low camera angle so that the audience was often “looking up” at the characters.
If you count cultural knowledge, I’ve posted before: I was once playing with my daughter before bedtime, and for some reason she grabbed my finger and put it on her nose. I immediately said in my best Yakoff Smirnoff voice, “In Soviet Russia, nose gets you!”
As my only audience at the time was five years old, I was rewarded with nothing but a quizzical look. It probably wouldn’t work for anyone under 30, for that matter.
Doesn’t require multiple fields of knowledge, but it is fairly esoteric:
Feynman and Heisenberg go on a road trip, Feynman driving. Heisenberg starts getting nervous and tells Feynman to slow down, or he’ll get a speeding ticket. Feynman says, “Don’t worry, Werner. I’ve been watching the speedometer carefully, and I’ve been driving at exactly the speed limit.”
Heisenberg gets really angry. “You idiot! Now we’re completely lost!”
…But nobody laughs when I tell it. Something wrong with my delivery, I guess.
What’s a polar bear?
A rectangular bear after a co-ordinate transform.
If you want a shorter (and maybe easier to deliver) version, I heard it like this:
Heisenberg gets pulled over while driving on the highway. The officer asks him, “Do you know how fast you were going back there, sir?” Heisenberg replies, “No, but I know exactly where I am!”
My contribution:
Knock, knock
Who’s there?
Interrupting coefficient of friction
Interrupt-
Mu!
Ok, so it’s only really one field, but it also references another joke, which gets pretty specific (interrupting cow/moo! for the uninformed)
Ad maiah v’esrim is a birthday wish which means “until 120” in Hebrew. 120 years is sort of the maximum age you can aspire to according to Jewish lore; it’s how long Moses lived.
Meanwhile, red blood cells live for about 120 days.
If Schroedinger is the passenger, the cop then opens the trunk and says “Do you know there is a dead cat in here?” and Schroedinger answers “I do now”.
Similarly: A black cat, a grey cat and a white cat start at the ridge of a pitched roof of uniform composition and slope. At t=0 they begin sliding under the influence of gravity. Which cat falls off the roof last? The one with the highest m
I think that’s very funny.
What’s an anagram of Banach-Tarski?
Banach-Tarski Banach-Tarski.
(I either stole that from here or an even geekier forum :))
Are Calvinist ministers pre-ordained?
Ornithology joke I made up yesterday:
What does a minister say when marrying two swans?
“In cygnus and in health…”
Love it!
How many church elders of [insert your denomination here] does it take to change a light bulb?
Change???
Then Hanna Arendt was right: Eve’ll be banal.
Haha you guys are great! I get the physics, math and engineering jokes for sure… but some of them are really stumping me! The pedant’s revolt? Anna Held? Can someone explain these to me? Sorry for being so lame

You stole it from me:
Wat Tyler (pronounced like ‘What’) was a leader of the Peasants Revolt in England…
As it’s about maths, I’m going to say I researched it from you.
(Also, thanks for giving me a joke to put in my dad’s birthday card that year - he really enjoyed it.)
If it makes you feel better, I chuckled when I read it.
