OK here is how this game works:

I will start it by impersonating someone, or some type of person. You have to guess who I'm impersonating. Then I will reply with the answer, and who ever gets it right gets to impersonate someone else.

If nobody is getting it after quite a few replies, the person who started it gives a hint. If nobody gets it after at least 20 tries, the person says who it is and then makes a new impersonation.

Example:

jpbtennisman: who am i: "We need to figure out a good strategory"
denniswrenn: uh i dunno
filburt1: what?
parksie: you are George W. Bush
jpbtennisman: that is right now parksie impersonates someone
