I think when you do comedy you play by a different set of rules. No one really wants you to be in that good shape. Being in good shape implies a level of vanity that isn't necessarily funny.
My friends say 'Man you're going to have kids sleeping on pillowcases with your face on it! You're going to be on toothbrushes and magnets and stuff.' I guess now that I'm a dad I'm thrilled about that.
