tl;dr: They were down there talking about math one afternoon and the owner of the deli was trying to take the order from one of them and he was a little bit too preoccupied with mathematics to fully engage in the sandwich ordering process.
"What's purple and commutes?" "An abelian grape"
"What's yellow and equivalent to the axiom of choice?" "Zorn's Lemon"
Evidently there's something inherently funny about group theory.
Does anyone remember the story about the famous mathematician at (I think) Princeton, who would always pick 3 as a random number in his examples. ("Let's pick a random number, say 3...") And then he ended up mentoring an entire generation of mathematicians who adopted his habit. And everyone would always "randomly" pick 3. It became a thing. It's kind of a variant on the "let L be a group" because the joke relies ent…

Typically, you'd use G when picking a variable name for a https://en.wikipedia.org/wiki/Group_(mathematics) The equivalent programmer joke might be something like "int str;" or "string array_length;" It's kind of funny in the "oh that's a really bad joke" kind of way :)
"Let ε Or a similar but more blatant telling of the original joke would be "Let ℵ₀ be a group."
Our real analysis lecturer once put this question on the blackboard (with sum as the proper scientific sum notation).
Even though we all knew the answer as trivial it took most of us some time to figure it out in such screwy notation (his point was that our mind is not invariant WRT notation, do not make up monsters when the normal schemas exist)

Is that a reference to the hilariously broken PS3 RNG? For those unaware, the PS3 was jailbroken because their RNG always returned 4.

I still don't get it. :/
