Damon's an intelligent, well-spoken guy, as he demonstrates in many interviews (especially this one re: teachers). Naturally, he plays plenty of intelligent, well-spoken characters, as well as action heroes. So when he shows up leading a comedy it's always a nice surprise, but sometimes he really surprises, showing up in movies or on TV shows you had no idea would involve even a hint of Damon.
Even better than knowing Damon will pop up in a film is when you don't. Those awesome surprise cameo moments (usually comedic) that happen in movies that make you go "no way, was that?!" Yes it was. It was Matt Damon. And he was awesome. These are the very best Matt Damon cameo, so vote up your favorite (usually uncredited) appearance below.
This was in a time when Damon had both the Ocean's and Bourne franchises up and running. Basically, he was one of the movie stars. Him popping up in a teen sex comedy was already surprising, but that he was a nearly unrecognizable tattooed, pierced rocker stealing the hero's girlfriend made this cameo the high point of EuroTrip.

In a tiny cameo during Chasing Amy, Matt plays Executive #2, a thoroughly '90s cool guy who just doesn't really get it. Damon is friends with both writer-director Kevin Smith and (obviously) the star of the movie, Ben Affleck. Nice to see friends helping friends with movies.
