Is it just me or do chemistry teachers say corny jokes alot in class? I know mine does, it's actually pretty funny...
I'm a chemistry teacher and I do...
The chemistry department lift at the University of Sussex in England used to have this graffiti on it:
Potassium ethanoate rules, CH
3CO OK
A couple of my favourite physics jokes:
Einstein, Newton and Pascal were playing hide and seek. It was Einstein's turn to count, Pascal ran off to hide but Newton just drew a sqaure, 1m along each side on the floor and stood on it.
When Einstein turned around he said, "Newton, I've found you already". No, replied Newton, you've found Pascal.
A Higg's bosun walked into a catholic church, the priest sent hm away saying "Sorry, we don't allow bosuns in here", the bosun replied "How are you going to have mass without me?"
