"Incontinentia... Incontinentia BUCKET!" is awesome. The whole Wome scene is hilarious.

But that's redundant - the whole Monty Python entity is hilarious.

"Nobody expects the Spanish Inquisition!"

"I find your American beer like making love in a canoe."
"Why's that, Bruce?"
"Cause it's smurfing close to water!"

"Spare a talent for an ex-leper?"
