Dave Chappelle surprised fans at the Laugh Factory Sunday night by showing up unannounced for a set at around 10:30 p.m., and then remaining on stage for the next six hours straight.

Laugh Factory owner Jamie Masada says Chappelle’s set was the longest performance by any comedian in the venue’s 28-year history. It began at 10:36 p.m. Sunday and ended at 4:43 a.m. on Monday.

“It was just one of those nights,” Masada said of Chappelle’s appearance. “He had everyone laughing for six hours.”

The marathon session only lost about a dozen of the 150-plus audience members who were present at the beginning of Chappelle’s set, which covered such topics as President Bush’s buffoonery, Comedy Central’s decision to hype Carlos Mencia after Chappelle abruptly left the network, and Michael Richards’ use of the N-word on the very Laugh Factory stage last year.

D.C also made fun of Masada’s post-Richards decision to impose a fine on any comic who uses the “N”-word onstage.

“I was his punching bag for a half hour,” Masada said. Needless to say, Dave was fined $2200 for his multiple use of the N-word throughout the six-hour run.
