Well, that didn't take long. Weeks after ending his long-running CNN show, Larry King has booked another TV gig.

It's not what you'd expect, though. According to TV Guide, the newsman has booked a cameo as himself on the ABC sitcom 'Better With You.'

King will shoot the guest spot next week, and the episode is scheduled to air in March.
