Yesterday on NPR they did a story on the anniversary of one of the worst years in music, 1974. I don't know if I agree, but there were some pretty awful tunes that came out that year (not that I remember - I wasn't born yet). Anyway, they played a bit of "Mockingbird", the doomed duet between Carly Simon and James Taylor, saying that it was lampooned in a few films. Now I know I've seen one that does it in a subtle way, but I can't think of which film it is! It is driving me nuts. If you know what film includes the quote:
"Mock - "
"yeah"
"-ing-"
"yeah"
"-bird."
"yeah"
then please let me know. I'm thinking it was a recent Pixar movie. But maybe not. Help!

edit: Here's a link to the story, where they play a snip of the song (and other disasters) from 1974.
