The Great Petrie Fortune - S5-E6
Revealing mistake: The great-grandfather Petrie was just Rob Petrie dressed as a really old man. The lamp in the movie is also one that has been in Robs house and Sally's house in a few of the episodes.
Revealing mistake: While Rob is having a boxing match and Laura is really mad at Rob. I noticed that some of the punches are actually to the hand region when Rob is in the corner and supposedly gets a boxing glove to the face. They aren't hitting each other that hard either.
Revealing mistake: Millie (in Rob's dream) tells Jerry (Doc) that "Big Bad Brady is already dead" yet we see that Brady is up there trying to not move, laugh or breathe. He's still alive if his stomach is still going and moving the whole time. Also when he aims his pistol at Rob, he's aiming it at Rob's hat. Not at Rob's arm. Which is where Rob said he got "shot".
