I don't understand the parents... SPOILERS
LOTS OF SPOILERS BELOW...
Okay so at the end of the movie the new mom is the person who was the babysitter's roommate. That explains why there wasn't a bed (probably on purpose). Also seems like she brought her to the bulletin board for a reason.
So who are the parent's he has during the movie, the mom and the dad she is babysitting for? Why would all three of them (mom, dad, roommate girl) be in on it? The dad says he didn't chose this and they want to get him out of town. Or maybe he pocessed the parents? Or pocessed the roomie at the end of the movie?
Did I miss something? If not, then what are your theories?
