We just happened to stumble into this one. We stopped by the Adult Swim booth and saw folks lined up to capture slips in this head cone thing. We thought the slips were like currency that we could turn in for trivial prizes. That was good enough for us, so we get in line. As Josh is scooping up the slips, I hear someone say "He's got it!". We didn't even understand until the attendant told us that Josh had just captured the one slip that would get us two rare tickets to the Metalocalypse Dethklok concert to be held that night on the aircraft carrier USS Midway museum.
