Continuity mistake: During family counseling, Gord throws the bust through the window which breaks the glass and the wooden support frame of the panes, and there's nothing sticking out.

Deliberate mistake: In the scene where Gordon is in the shower wearing his dad's scuba gear and his dad throws the soap on a rope into the toilet, Gordon dives into the toilet to retrieve it. During the camera shots from beside the toilet, you can see that the back of the toilet has been removed so as not to block the view of Gordon with his head in the bowl, but in the other shots, you can see the back of the toilet just fine.
