At last night's upfronts presentation at Carnegie Hall, CBS threw up a surprise guest. Miss Katie Couric took the stage with Les Moonves to promote her new gig as the anchor of CBS News.

"Katie thought it would be odd to not make a brief appearance," said her spokesman, Matthew Hiltzik. "NBC was informed of her intentions, and she did not receive any objection."

And had they objected, Katie would have made NBC pay by spending 10 minutes of the Today show spewing a pointless random monologue on difference between bootlegs and flares.
