Chemistry Joke

Listen up, buttercup. This is so easy even YOU should get it. It's a chemistry joke, right? In chemistry, a "reaction" is when chemicals do stuff together. The joke is that nobody reacted to the joke, but it's ALSO a chemistry term. Get it? I bet you still don't. You're probably one of those chuckleheads who thinks "sodium chloride" is something you put on your driveway in winter.
