Host With the Most

When New Yorkers get late-night jitters, who better to turn to than Letterman; remember how good he was post-9/11? But Dave has been awol with shingles, leaving A-listers like Whoopi (and Z-listers like Tom Dreesen) to fill in. Here, the best and worst rent-a-hosts.

That old Joey and that weird climax of his.”
