The Who's Who of Comedy

Jim says he's amazed by his 20-year-old daughter, Jane. "She's incredibly talented," he says. "She's a jazz musician and singer/songwriter, and she's just going to really surprise a lot of people. ... I sit there, and I just marvel at her."

Jim is also actively involved in the life of another youngster, Jenny's son, Evan. In September 2007, Jenny came on The Oprah Show to discuss Evan's battle with autism. At that time, she described Jim as "the autism whisperer."

"[That] is a huge compliment," he says. "I think it's just because I'm interested, you know? I really want to find out how his mind works."
