Continuity: In the episode, The Solomons and Dr. Albright go on a "Murder Mystery Weekend". Toward the end of the episode Tommy and Sally are in a hallway upstairs. Sally is carrying a lit candle. Tommy says to stop waving it under her face because it makes her look spooky. Suddenly the lit candle disappears, never to be seen again - the only place it might have been put is a long table to Sally's right, about 5ft away with some kind of arrangement on it, but it's not there.

Revealing: Near the end when Randy is driving away with Harry you can see that the steering wheel doesn't move when Randy turns it.
