The first one I remember singing on stage was 'Somewhere Out There' from 'An American Tail.' I was around 7, and my choir teacher at school asked me if I would sing it. My parents told me that I needed to move around the stage, so for the entire time I just walked back and forth from side to side while I was singing - there's videotape of it.
I wanted to be the best street fighter in Houston, Texas. And I thought if I got a trophy or two, I'd go back home, and everyone would be afraid of me. I had one fight in '67, the first one. In '68 of October, I was an Olympic gold-medalist, a dream come true, with a total of 25 boxing matches.
Stand-up can take you in so many different places, man. So many doors can be opened up from stand-up comedy, and the first one that was opened up for me was acting. But you can go from acting to being a TV personality to being a radio personality to being a writer to being a producer, to just being a visionary, to voiceover work.
