Continuity mistake: In the scene where they are in the all you can eat restaurant, when PaPa Klump farts into the candle causing the curtain to catch fire, when they first show the curtain after the 2 men put out the fire, there is clearly a burn mark on the edge of the curtain. However, when they show the curtain again, there is no burn mark.
Continuity mistake: At the end of the movie when Denise is looking for Sherman at his house and she's asking Papa Klump where he is, Papa Klump says he was talking about eating some guy and then she figures that's Buddy. But when she figures that out she grabs the newspaper Papa Klump is wiping his hands with and opens it and sees Buddy's picture on it. Now how did she know Buddy was on the newspaper when Papa Klump was wiping his hands with it before he told her that?
