Found the following website called Overplot created by Google employee Mihai Parparita which maps funny conversations people overheard in New York onto a Google Map.
Below is a sample of quotes from the site:
Dad: All I know is right now, somewhere, an artist is sitting back and laughing at us.
Little girl: Or if he’s in Australia, he might be sleeping.
Subway conductor: Please enter the train as human beings, not wild animals.
Dim bulb: I’d say the odds are pretty good. At least fifty-fifty.
Dimmer bulb: No, they’re not that good. More like forty-forty.
Thanks to Google Blogoscoped for the link.
