To Quote The Hitchhikers guide to the Galaxy.
One of the things Ford Prefect had always found hardest to understand about humans was their habit of continually stating and repeating the very very obvious, as in It's a nice day, or You're very tall, or Oh dear you seem to have fallen down a thirty-foot well, are you alright? At first Ford had formed a theory to account for this strange behavior. If human beings don't keep exercising their lips, he thought, their mouths probably seize up. After a few months' consideration and observation he abandoned this theory in favor of a new one. If they don't keep on exercising their lips, he thought, their brains start working. After a while he abandoned this one as well as being obstructively cynical.

Waldorf: Well, it wasn't bad...
Statler: Uh, there were parts of it that weren't very good though.
Waldorf: It could have been a lot better.
Statler: I didn't really like it.
Waldorf: It was pretty terrible.
Statler: It was bad.
Waldorf: It was awful!
Statler: It was terrible!
Waldorf: Take 'em away!
