If you’re David Letterman, and you can’t do your nightly “Late Show” gig, who do you call? A CBS spokesperson stated that Letterman had to go home sick with a stomach virus, but he was able to find a last minute fill-in to handle his "Late Show" hosting duties: Adam Sandler.

Sandler was already scheduled to appear on the show as a guest, along with actor Don Cheadle, to promote their new film "Reign Over Me," a drama about a man who reconnects with a college roommate after losing his whole family in the Sept. 11 attacks.
