Aamused in Austin, TX

LOS ANGELES, California (AP) -- "Tonight" host Jay Leno might want to consider wearing referee stripes on Wednesday's show when Ann Coulter and George Carlin are his guests.

Coulter, the acid-tongued conservative with a new book out, and Carlin, the quick-witted, antiestablishment comedian who's in the voice cast for the new animated film "Cars," were booked at separate times for the NBC late-nighter, a spokeswoman said Monday.

But the duo's meeting could produce serious fireworks for "Tonight," which usually limits its political fodder to Leno's bipartisan monologue jokes.
