Buffalo, New York - Comedian Dave Chappelle played an impromptu show in Buffalo, and gave all proceeds to the victims and families of last month's mass shooting.

Chappelle booked the last minute gig at Shea’s Performing Arts Center only four days prior. The 3,019 seat arena quickly sold out.

"He said, and I’m paraphrasing, 'I came here to Buffalo to recognize the victims and for these families,'" Kevin Sweeney, the venue's director of marketing and communications, told the Rochester Democrat and Chronicle.

The comedian confirmed this at the end of the performance, letting the crowd know that a few families of victims were in the audience, and he would be donating all ticket sales for the event to them.

Last month, a gunman opened fire at a Tops Friendly Market in a predominantly black neighborhood in Buffalo, killing 10 people in a racially motivated attack.

Chappelle also faced a violent incident last month when a man wielding a knife rushed the stage at the Hollywood Bowl and attempted to tackle the comedian. The attacker, Isaiah Lee, was reportedly carrying a replica gun with a knife blade at the time.

It's always good to see a celebrity using their influence for a good cause and Dave Chappelle's gesture was widely praised on social media.
