At one point in the episode Denise, Vanessa and Cliff watch a movie. When its over Vanessa says "Dad that movie was so much better than those old black and white things you make us watch."
This is an odd thing for Vanessa to say when she was really into B&W movies herself just a few episodes earlier (in #137 "Elvin Pays for Dinner"). She was such a big fan of those movies she even tried to get Rudy to like them.
Vanessa: "You can't tell me to leave Mom alone, only Mom can tell me to leave her alone. Mom!
Clair: "LEAVE ME ALONE!!!"
