Re: One out of four
Dennis Moore (I assume you mean the Monty Python sketch): A man is exploited by the poor and exposed as an idiot.
Parrot: The parrot's DEAD. It's funniest when he whacks it on the table.
Lumberjack: Okay, I'll give you that one. Humor based largely on the incongruity of a transvestite lumberjack.
Blazing Saddles: Good grief, you've got to be kidding. It's wall-to-wall violent slapstick! "Have you ever seen such cruelty?"
