After 4 Hours of Quake 3
me (in hypnagogic state): Hey Allen, which team are you on?
roommate: Uh.....red team.
me: (scathingly) Pfft. Red team sucks.
My other roommate has the unusual habit of sleeping with his eyes open and there have been plenty of times that I've carried on short conversations with him even though he was far from conscious. A memorable one:
me: I'm going to the vending machine, August, how many cookies do you want?
me: One? You sure you don't want two?
me: Ok, do you want anything to drink?
