Today’s Late Show with David Letterman will have something different—an absent host. Letterman came into work for a taping of the show earlier today, but had to leave because of a stomach bug. What to do when your host is sick? In this case, the show looked no further than one of the guests—Adam Sandler. That’s showbiz, folks. The show must go on, even if your fearless leader is throwing up elsewhere. Luckily, he had already taped Wednesday’s show and is being pre-empted on Thursday and Friday for NCAA basketball. Question is, does Sandler deliver in a pinch? I know I’ll be tuning in to find out. OK, you caught me—I go to bed before Letterman comes on, so I’ll DVR it for another day.
