I played a Halo 2 clan match against a group of people acting like idiots. It was probably the most fun match of any online game I've ever played, though. Their name was The Suicide Squad, or something like that. Instead of fighting against us, they lined up perfectly and marched their way across the map, into our base (it was a CTF match) and up to our flag. The entire time they were chanting "Flag. Flag. Flag. Flag." They would jump up and down, still staying in line, and would just come back chanting when we killed them. Eventually they started following one of our players around, chanting his name like a creepy assortment of Spartan groupies. It was hysterical and awesome. There should be more idiots like that online.
