ROTFL UWW!!!
I love this one:
Cleese: "I need a license for my pet fish 'eric'"
Palin: "There's no such thing as a fish license"
Cleese: "Yes there is! I got one for my pet cat 'eric' as well"
Palin: "There's no such thing as a cat license either"
Cleese: "Well, what's this then?"
Palin: "That's a dog license with the word 'dog' crossed out and 'cat' written in in crayon"
CLeese: "So? I have to protect myself from the Cat Detector Van. It can pick up a purr at 500 yards!"
Palin: 'You're a looney"
