Eh, could be worse for Leno, Huckabee's a pretty good guest, as "Daily Show" fans already know.

NEW YORK (AP) — Robin Williams will be David Letterman’s firstguest upon the return of his “Late Show” on CBS Wednesday.
The appearance of a Hollywood A-lister who can talk a mile aminute may be Letterman’s way of quickly trying to draw adistinction between his show and his late-night rivals, who arewithout writers and may also have trouble booking majorentertainers as guests.
NBC’s “Tonight” show said Monday that Republican presidentialhopeful Mike Huckabee will appear on Jay Leno’s first show backWednesday.
Letterman announced Friday that his production company,Worldwide Pants, had reached an agreement to have his show returnwith writers despite the continuing writers strike, which beganNov. 5. The deal also allows writers to return to Craig Ferguson’slate-night show, also owned by Worldwide Pants.
The late-night shows hosted by Jimmy Kimmel and Conan O’Brienare also returning Wednesday but have said little about who will beappearing.
