In the episode Peggy and the Pirates, Al's toilet in his room gets clogged. He opens up a safe in the wall from the left (where the knob is) to the right (where the hinge is). He takes out 1 of 3 plungers and shuts the safe door, but not all the way. The toilet takes that one. Then, when he reaches for another one, the safe door is open and opens from the right (where the knob is) to the left (where the hinge is).
