Well, that's only because he hasn't had any needlepoint prep time. Anyway, what do you think he keeps Harold around for? Harold's a master with the cross-stitch. (As seen in Batman's Friends and Foes #54, "The Nefarious Needlepoint Nonsense!," March 1957)
A long-time professional at battle insane criminal masterminds based on Alice's Adventures In Wonderland like the Mad Hatter, Tweedledee and Tweeledum, and Prime Minister Benjamin Disraeli, Batman's pretty well acquainted with humor of the absurd. It's been rumored the Dark Knight has up to three dozen joke writers on staff to generate these quips for him, most of them locked in shackles in a lower level of the Batcave. They also script-write the TV show Whitney.

But if there's anything Batman does well, it's dark. His favorite type of night? Dark. (Also, his favorite type of knight.) His favorite publishing company? Why, Dark Horse, of course. His favorite kind of candy bar? Milky Way Dark. The way he takes his coffee? Milk, two sugars, in a styrofoam cup. And his favorite type of humor? Oh, man, you gotta believe it's darrrrrrk.

Even Harley had to laugh at that one.
Look, I know. Batman is not gonna give stand-up greats like George Carlin, Lenny Bruce or Bill Hicks a run for their money on the stage of Dangerfield's. (Then again, let's see one of them bring in the Joker!) But even if Batman isn't the number one jokester in the DC Universe, at least I'm sure we can find somebody who's worse at telling a joke on Earth-1, right?

And that, ladies and gentlemen, is why they keep Green Arrow around the DC Universe: so nobody else feels like they're the worst at anything.
