Chris Klein auditions for Mamma Mia. Oh yeah, it's real. NBC Universal had the YouTubes take it down because they owned the footage. But they couldn't stop College Humor from getting it before it was yanked down.
Who did all the cocaine? Chris Klein did all the cocaine.
I would also like to take the time to recommend Klein's performance in Street Fighter: The Legend of Chun-Li. Klein plays rogue Interpol cop Nash, who is apparently a coked out, overacting lunatic as well as an international detective. It is a virtuoso performance. He's the C-Level Nic Cage. It's a shame the clip doesn't include a montage of the 50 or 60 times he yells his catchphrase "NASH... OUT!!" in the movie.
