Dave Chappelle has been spotted again — this time in Hollywood. According to Variety, the stressed-out comic treated audiences at Hollywood Improv and the Comedy Store to some unrehearsed stand-up on Wednesday night. Chappelle apparently showed up unannounced at both venues, telling folks he just flew into LAX and was in the mood to perform. Hopefully, he'll soon be in the mood to do his freakin' show!!!
