Whenever I realize I'm being a goofball, I write it down. When I release the joke onstage, I love watching the effect it has on the audience. No one wants to see someone talk who takes themselves too seriously.
They killed my character off and as God would have it, just when they told me I would never work again, I got cast in a little program called Roots, and as they would say, the rest is history.
You've got to know your limitations. I don't know what your limitations are. I found out what mine were when I was twelve. I found out that there weren't too many limitations, if I did it my way.
