Dave Chappelle -- Who Knew I Was Famous?

Dave Chappelle attempted an impromptu stand-up routine outside of the Pioneer Courthouse Square in Portland early this morning -- but Dave's ignorance of his own popularity ended up ruining the show.

For some reason, Chappelle wasn't expecting many people to show up, arriving at around 1 AM carrying a tiny amplifier. Turns out over 4,000 people showed up, according to Oregonlive.com.

Dave ended up leaving at around 2 AM after explaining it was impossible to put on a show under those conditions.
