Duh. It's past my bedtime. Why am I here?!

Who asked that question? Homer Simpson or Matt Groening?

It's an interesting point, though. Who do you credit for a saying? It probably depends in part on (a) if you know who the character was, and (b) if you think that your interlocutor will, too. If you were to shout "Yabbadabbadooooo!" and someone asked you who said that, would you credit Fred Flintstone or whoever it was who wrote the script for Hanna Barbera? But if someone were to ask you who said "parting is such sweet sorrow", would you say Billy the Scrivener; or that it's from "Romeo and Juliet" Act 2, Scene 2; or that Juliet said it?

Which reminds me of a TV spoof on R&J from a long time ago with, I think, Frankie Howerd as a very, very effeminate Romeo. Such lovely legs in those tights! Juliet was someone like Hattie Jacques.

Juliet: "Romeo, Romeo, wherefore art thou, Romeo?"
Romeo: "'Oldin' up the bleedin' balcony, you fat git!"
