With 'The Proposal' coming out this Friday, we thought we'd take a look back at our favorite movie quotes from stars Sandra Bullock and Ryan Reynolds.

In the upcoming rom-com, Reynolds ditches beer cans, frat parties and characters with hit-it and quit-it tendencies (a la 'Van Wilder,' 'Waiting') for a tamer role (though he doesn't abandon partial nudity, for which many fans are grateful). Bullock ditches her uber-likability to play the demanding over-achieving boss who blackmails him to marry her. We bet we know where that's headed ...

In the meantime, we've compiled a list of our fave quotes from America's sweethearts (yeah, we went there), from Bullock's charming, often no-holds-barred, and always fast-paced one-liners to Reynolds' R-rated vulgarities. Read on and tell us your favorite Sandra or Ryan quotes.
