Gotta check out this hilarious website -- http://www.almostmetjew.com/. It's for people who want to connect with someone they met but who are missing their name / contact details.
Random sample include the guy who can't remember the name of his Friday night dinner hostess but knows she likes Rice Chex (how did he get there in the first place?), the pervert who's trawling Only Simchas to find pictures of hot girls to date, and the guy who thinks a girl he went out with 2 1/2 years ago will be flattered enough by his ad to try again -- although he can't remember her name...
I think we have a hit on our hands.
