You remember the show, "Bananas in Pajamas?" It was a tv show geared toward kids with two bananas, B1 and B2, who wore pajamas all the time. Their song went "Bananas, in pajamas, are chasing teddy bears." Therefore, for a Halloween party, this fools dressed up as B1 and B2 and chased around their roommate, who they made dress up like a teddy bear.
