A West Nyack comedy club has canceled a comedian's performance after he allegedly made disparaging comments about the victims of the Boston Marathon bombing, Newsday has learned.

Levity Live canceled Paul Mooney's 7 p.m. Sunday show after about 20 people walked out of the club Saturday night during his stand-up routine, a club manager told News12. The manager declined to give his name.

The club, located in the Palisades Center Mall, listed Mooney's Sunday night performance on its website earlier in the day but pulled the show by afternoon.

"Paul Mooney last night at Levity Live said white people in Boston deserved what they got," said a Twitter user.

Attempts to reach Mooney or club management by Newsday were unsuccessful.

The canceled show was the last of six appearances, including last night's sold-out 9:30 p.m. show at the comedy club.

Mooney has a reputation as an African-American comic who pushes the envelope of propriety, especially on racial issues.

"Paul Mooney is one of the most dangerous and brilliant comic minds of our time. This is not a show for those considered easily offended," says a bio of the comic from Caroline's On Broadway, a Manhattan comedy venue.

Beginning his career as a writer for Richard Pryor, Redd Foxx and "Saturday Night Live," Mooney also appeared regularly on the popular "Chappelle's Show" on Comedy Central.

The club was accepting donations to help the Boston victims before the show, the club manager told News12. Audience members who left the show in disgust were given refunds, he said.
