They always use the word 'insult' with me, but I don't hurt anybody. I wouldn't be sitting here if I did. I make fun of everybody and exaggerate all our insecurities.
I don't care if the average guy on the street really knows what I'm like, as long as he knows I'm not really a mean, vicious guy. My friends and family know what I'm really like. That's what's important.
Among my friends, I'm not a little Boy Scout, and they love my humor, thank God.
Some people say funny things, but I say things funny.
You can't study comedy; it's within you. It's a personality. My humor is an attitude.
