Word is that Mitt Romney is preparing a series of “zingers” — short, memorable digs at Barack Obama — to liven up the debate on Wednesday. A few of them have leaked out to the press:

I know you are, but what am I?

Did you get that idea from your Muslim dad?

The last time I heard that one I fell off my dinosaur.

Whoa, bro — don’t mug me!

You’re the President of the United States Of America — not the President of me.

Aides report that Romney’s biggest problem with the zingers is not breaking up when he delivers them.
