Well, anyone who's watching The Late Show right now probably realizes that David Letterman's not there.

Apparently, Dave showed up to work today but took ill with a stomach problem. It must have been pretty bad, because the only things that have kept Dave off the air in the past were a bad case of the shingles and heart bypass surgery. According to the AP, this is believed to be the first time Dave was not able to go on after showing up for work.

Anyway, tonight's main guest, Adam Sandler, was recruited to fill in, and seems to be doing an OK job of it so far . And he was even able to pull in his Reign Over Me co-star, Don Cheadle, as a guest, so the movie promotion machine didn't skip a beat. Oh, and as a privilege of hosting, Sandler decided to bring his bulldog, Matzoball, up on stage. Awww.....
