Continuity mistake: When Clifford (Martin Short) and Uncle Martin are talking about Clifford's prank at the gas station, the entire thing is being recorded by a taping device in the room. Uncle Martin says. "I'm gonna punish you, and that means Dinosaur World is out." And Clifford responds with, "I don't understand." However, when Clifford later comes up with an idea to use the tape recording in another one of his schemes, we again hear Uncle Martin say ".punish you, and that means Dinosaur World is out." BUT we hear Clifford respond with "That would be a mistake." Judging that this is a recording of the previous conversation, I don't see why Clifford should be saying something completely different than what he was saying before.
