However, the end was handled differently: Brian was understood to just be Brian, that's who he is, and Rush was revealed to be a soaring Eagle flying high over his protectorate of America, and it takes a little memory to remember who Brian is: A Marxist dog agitator, that spends his life complaining about the free food, and trying to bugger Lois, the wife of his meal ticket. Yep, that's Brian.
The eagle ending was good.
