I don't feel an obligation to give everyone a hard time, but when they're important people, it's fun.
I always rib people, but nobody ever gives me a hard time. I don't know why. Maybe they're afraid of what I might say. There's probably a lesson in that somewhere, but I don't know what it is.
I have no idea what I'm going to say when I stand up to give a toast. But I do know that anything I say I find funny.
