Check out InPassing.org, a compendium of things overheard on the street in Berkeley, CA. A sample:

"...A really nice guy, and he just loves AC Transit. He's got a picture of every bus -- he even drove down to Freemont to take pictures of the busses there. If you're ever trying to convince him to go somewhere, all you have to say is, 'But think, you could look at the busses while you're there...'

"He better not be taking pictures of my bus."

--A passenger and the driver on an AC Transit bus

All very amusing. (Link via Laura at My Side of Things.)
