This obviously isn't from the movie, but the South Park bit pitting Jesus versus Satan in a pay per view fight was one of the funniest things I ever saw. Jesus was maybe 95 pounds soaking wet, and Satan was a 300 lb bruiser. Every single person in the town, except one, bet on Satan to win. You figured it was the priest, who was admonishing everyone to stand by Jesus.
The fight starts, Jesus taps Satan, who immediately drops flat and gets counted out. Turns out that the only one who bet on Jesus was Satan, and he threw the fight to clean up on all the bets. He then berated all the townspeople for having no faith in Jesus, thereby letting Satan screw humanity again for their lack of faith. Absolutely classic.
