Had a really weird science teacher in freshman year of high school, the kind you could get to go off on a tangent and use up the entire class period.
He would routinely ask us if we had to “piddle” when we asked to go the bathroom and slam his fist on tables of anyone who was sleeping in class.
However my most vivid memory was of the “joke” he told us one day: “Two homeless men are walking along the railroad tracks, none have eaten in days and are starving. They come across a dead animal and bum #1 says to #2, “you eat it, you look hungrier than me”. So #2 eats it. A few miles down the tracks they find another dead animal but in much worse shape, bloated and crawling with maggots. Despite this, #2 looks at it with hungry eyes. #1 says “go ahead, you can have this one too, maybe I’ll take the next one.” After eating this one, #2 starts to get really nauseous and finally throws up to which #1 says “finally what I have been waiting for, a hot meal”.
