He told us this really corny joke. But i was laughing my ass off because i love corny jokes, but here it is. "How do you tell a girl chromosome from a boy chromosome? You pull down their genes!" Did this tickle your insides a bit? Or do I just have a lame sense of humor?
Why do science teachers always tell these awful jokes? Here's one mine told us: Okay, one day there was a proton and an electron walking down the road to go see a movie. And the electron said to the proton, "Did you remember your wallet?" and the proton said "Yeah, I'm positive," >_<
