First off, this apparently aired on Jimmy Kimmel Live last night. I've grown pretty tired of Sarah Silverman's small number of jokes (her act is just: I'm crude and I have funny songs) especially after her show on Comedy Central really played it out, but this is hilarious. There's another version on YouTube with the intro where she sets up the clip for nearly a minute, but it didn't have anything funny, so here's the version that jumps right into the video (the longer, crappier one is here).
I'm F--king Matt Damon
Thanks to YouTube's related videos, I then found The Departed, The F'--king short version, which basically compiles all the F-bombs (and some other profanities) from the movie. But it does include a few longer clips and the result is quite funny (this one is not only NSFW, but it's also full of Departed spoilers, so if you haven't seen it yet, go watch it because it's great!).

There's a strong parallel between the first video and the song Matt Damon sings in Eurotrip:
