Huh?

Here's The New York Times review of Jim Holt's book on jokes. It's by William Grimes, who writes obituaries for the Times--is he the right choice?

Anyway, good or bad, this bit near the end raised my eyebrows.

Even worse, the jokes are feeble. “Skeleton walks into a bar and says, “Give me a beer and a mop.” Huh?

Huh? What's the "huh?" for. I thought he was going to show us a weak joke. I actually like this one, but even if I didn't, a "huh?"? It suggests confusion. Okay, Grimey, we know you don't like the joke, but do you get it?
