This is the episode where Becky stops speaking to Rosanne and locks her door. Rosanne goes to get a screwdriver to take the hinges off the door.

There is a reason that they do not actually show her removing the hinges....she is on the wrong side of the door to do it. The door opens into Becky and Darlene's room and the hinges are on the INSIDE. Rosanne is standing OUTSIDE. There is no way that she could remove the hinges.
