Stephen takes a dive

Colbert threw his match with Sean Penn in the "Metaphor-Off." But it's national poetry month, so it's okay. Good theater and some good metaphors, though none by Sean or Stephen . . . The best came from poet laureate Robert Pinsky, who served as 'moderator'.

The metaphor that got it started was an antrocious construction of Penn's, address President Bush: "and the smarmy pundits in your pocket who bathe in the moisture of your soiled and blood-soaked underwear."

Isn't that a doozey? And what's really scary is Penn was reading from prepared notes! No wonder Stephen jumped all over it.

But I'll be brief.
