It used to be that if you got on 'The Tonight Show,' your career was made. Now, if you're on 'The Tonight Show,' maybe 14 more people show up to your gig in Tulsa.

People don't know this, but early in your career, you don't just glide on to The Tonight Show.

My first appearance as a guest on The Tonight Show was in '81.

I did the 'Tonight Show' once, and I choked up. I get intimidated.

It used to be if you wanted to be a comedian, you used to just do sets. You'd go up three times a night, just get better, and then some people would see you and you'd do 'The Tonight Show,' and then boom, you're a comedian.

I've been on the 'Tonight Show' a million times, and I'd be embarrassed to do the same thing more than once.
