Plot hole: There are two cars driving behind the EPA truck containing Marge, Bart, Lisa and Maggie. When Homer uses the bulldozer to try and break the family out of the truck, the two cars behind the truck don't notice the bulldozer trying to destroy the truck. There's no way they couldn't have not seen the bulldozer since they were just behind it. (01:00:05 - 01:00:40)

Question: Why did Grandpa join the angry mob? It would make much more sense if he was either on his family's side or simply remained completely neutral.






Answer: The family doesn't treat him very well, particularly Homer. He may have wanted some revenge on them. Grampa is also a little senile.
