Laugh, and the world doesn't laugh with you.

I was just watching Ebert & Roeper. Ebert's probably the best-paid film critic in the world, but he clearly loves movies and you get the feeling he'd be working just as hard if he'd never made it on TV. Roeper, a fellow columnist for the Chicago Sun-Times, is luckier--not really a film critic, he fell into this plum job.

But a word of advice for both. When your partner makes a little "joke," don't laugh. You two are yokking it up way too much. I guarantee you're far more amused by each other than your audience is.
