i got a good example:
me and a friend was playing Co-op in Crash Bash. we played a stage where you slide back and forward in some kind of car to prevent some balls get inside your "goal". almost like soccer.
the 2 computers had more lives and they always owned us >_> suddenly we start talking about random things and was laughing so hard that we couldn't stand or sit right. we were just rofl. and we laugh about 10 minutes, suddenly we won the game xD
