Here's your hilarious joke:

Chemists in a pub After a long day, two chemists, Bill and Bob, go to a pub to unwind. Bob says to the barkeeper, "I'll just have a glass of H^2 0." Bill chimes in, "I'll have a glass of water too". They take a seat as he asks Bob, "Why did you refer to water with its chemical composition?" Bob did not answer, fuming that his assassination attempt had failed.
