The Ultimate Engineer Joke (18+ only)

Well, my friends.. if I get banned, know that it was fun (and I'll be back with a different name)

So a Physicist, a Mathematician, and an Engineer are all asked to prove that all odd numbers are prime

The Physicist says "1 is prime, 3 is prime, 5 is prime, 7 is prime.. Given the overwhelming experimental evidence, it's clear that all odd numbers are prime"

The Mathematician says "1 is prime (more or less), 3 is prime, 5 is prime, 7 is prime, and the rest go by a simple inductive proof"

The Engineer then says "Hold on, I'll prove that all odd numbers are prime once I get my dick out of this small child"
