I've heard that song before

Marc Ambinder makes some corrections:

2. Yesterday, I wrote that McCain adviser Charlie Black was taking a "leave of absence" from his lobbying firm. In fact, Black is resinging.

Ha-ha. This, in turn, calls to mind this exchange:

Homer: Look kids! I just got my party invitations back from the printers.
Lisa: [Reading the invitation.] "Come to Homer's BBBQ. The extra B is for BYOBB."
Bart: What's that extra B for?
Homer: It's a typo.

Whoops!
