What's your favorite thing to come out of Monty Python?

The entirety of Holy Grail, for starters. My high school history teacher said that it was one of the most realistic depictions of life in the Middle Ages ever put on film.

After that...

"What have the Romans ever done for us?"

"The roads!"

"Well, yeah. Obviously the roads. I mean, the roads go without saying, don't they? But apart from the sanitation, the aqueduct, and the roads--"

...and...

"Oh, we used to dream of livin' in a corridor! Would ha' been a palace to us. We used to live in an old water tank on a rubbish tip. We got woke up every morning by having a load of rotting fish dumped all over us! House? Huh."
