I have seen Lunchroom Manners at least two dozen times in my life and it always gives me a chuckle. I mostly remember it from Pee-wee Herman, but I also have some vague memory of this getting played on a late night show. Maybe Letterman or SNL or something local? My favorite part is when Phil is thinking about how messy his hair is and he is pulling this tiny amount of hair out-of-place to prove it.
Are you a Mr. Bungle?
