lol...that's pretty random and funny. At least it sounds like it was fun though so that's cool. Did you tell him you didn't know the mic was on? Though not quite the same, I was known for never talking on vent until on time when roommate had his push to talk and they heard me in the background...everyone went crazy for a while, haha.
I'm on there as SuperPoring, though lately I haven't played much on it. Lot of times I use my roommate's steam to play the 1873189719 games he has on it =P
