Remember the episode when Michael tried to hide the Betsy Wetsy Doll from Penny, well he tried 2 places, the stove and the refridgerator,,,,,,that's because the fake closet door in the kitchen is really a wall and he did not look at the closet door in the kitchen, NOT ONCE, that's the first place to look to hide something in a kitchen, the dam closet
Also, have you ever seen the chain attached, like it was locked on the fake kitchen closet door?
