As you review the back-and-forth over the late-night television battleground, you might wonder: What's the point? For me, when it's fun, a late-night show is like last night's Late Night With Jimmy Fallon, where he and Blues Traveler's John Popper played a little harmonica. There's nothing to it, really, except that if you have John Popper on your show, you should want to play harmonica with him, and it's that weird, warmly game quality that's really working for Fallon right now.

Also great from last night? Fallon's bit where members of the audience throw hot dogs through the mouths of cutouts of famous people in the news. You kind of had to be there.

Incidentally, if you had told me six months ago I'd be waving the flag for Jimmy Fallon, I would have had you checked for psychosis-inducing spider bites.
