Can you come up with some good dialogue (details inside)?

Inspired by This Question

Can you come up with a good paragraph or two of great dialogue using at least one great quotable line or phrase from each of the following three productions: Monty Python and the Holy Grail, Airplane, and Seinfeld?

You can add in other words and phrases, but you need to use at least one line or phrase from all three of the productions in your paragraph. Try to tie them together so they make sense, while at the same time being hilarious!

Go!
