Whatever happened to Dave Chappelle, the gifted comedian, writer, actor, and satirist whose "Chappelle's Show" ran for a mere two seasons on Comedy Central? His TV sketches were among the most brilliant and biting I've ever seen. Sure, Jimmy Fallon's send-ups of artists like Neil Young, Jim Morrison, and Bob Dylan are hilarious; his impersonations are dead-on. But Chappelle had a talent for writing and performing sketches that depicted stars at their worst and most outrageous. His parodies were often tasteless, usually non-PC, and always side-splitting. Fans and critics loved him. If you aren't familiar with Dave, or have forgotten just how talented he is, take a look at these classic "Chappelle's Show" spoofs of famous musical artists.
