ET's Lauren Zima caught up with the 49-year-old comedian at the charity event, where he opened up about his 3-month-old son Billy, and how he's doing after undergoing heart surgery hours after he was born.
"We're very grateful for everyone's kindness," Kimmel said, referring to the outpouring of public support his family has received since Billy's surgery. "He's doing really great and we're all very happy about that."
The Kimmel family was on hand to support the charity event, which benefits various children's causes. "It's obviously for a great cause and it's also a lot of fun," Kimmel said of the ping pong tournament. "I was here a couple years ago and I had a lot of fun. I was out of town last year but now I'm back!"
