There is a funny series of sites you should check out:
Overheard in New York the original site, and very funny.
Overheard in the Office
Overheard Everywhere
They also have Overheard at the Beach and Celebrity Wit, which are also funny, but not updated as regularly.
An example of the content:
Sorority girl to lit class: So she was all saying that I was totally against feminism if I insisted on shaving my legs. And I said she was totally against feminism if she insisted on being a whore!
Drunk middle-aged woman #1: Yeah, but I don't think...
Drunk middle-aged woman #2: The cops in the state of New Jersey all have computers in their cars. They pulled him over, and he wasn't even doing anything!
Drunk middle-aged man #1: Well, what did they say to you?
Drunk middle-aged man #2: They said I was driving erotically.
Enjoy!
Edit: Fubar kept messing up the link code, so I had to fix it.
