Apropos "sucks": The Beavis & Butthead sketch I like most is the one where Butthead (or was it Beavis? doesn't matter) dies and encounters St. Peter, who has a big book of Butthead's sins.

The ensuing dialogue goes repeatedly about like this:

St. Peter: What about the time when you (insert some infantile sin)
Butthead: heheheh - that was cool!
St. Peter: (in a deep, pedagogically slow, voice) No, Butthead, that sucked!

I get the giggles every time I just think about it. Talk about lack of maturity.
