Some people are a little creeped out by google ads, especially the ones that show up while you're reading your Gmail (the computer knows what I'm doing--eek!) but I just love them. Mostly because they turn up the oddest, most random things.
Such as this article about the world's oldest jokes.
Apparently, the oldest joke in human history is a Sumerian fart joke.
Also? Great name for a band:
Sumerian Fart Joke, playing one night only! With opening act Bored Pharoahs.
