You know the theory of cell irritability? If you take an amoeba cell and poke it a thousand times, it will change and then re-form into its original shape. And then, the thousandth time you poke this amoeba, the cell will completely collapse and become nothing. That's kind of what it's like being famous. People say hi, how are you doing, and after the thousandth time, you just get angry; you really pop.

I think all phases of one's career are serious if you take it seriously no matter if you are doing high profile dramatic pieces or not.

Something wild can happen to anybody and I caution anybody that walks out on the street, just settle your accounts before you leave the house every day.

Harold Ramis and I together did the ‘National Lampoon Show’ off Broadway, ‘Meatballs,’ ‘Stripes,’ ‘Caddyshack,’ ‘Ghostbusters’ and ‘Groundhog Day.’ He earned his keep on this planet. God bless him.

I'm just an obnoxious guy who can make it appear charming, that's what they pay me to do.

Movie acting suits me because I only need to be good for ninety seconds at a time.

There are a lot of actors that are more talented than me at Second City who quit it before they even got to a paying status. Weird luck. I had no other option.
