Well, Jimmy dressed up as Putin ... and a very special guest stopped by to lend Vlad an ear.
JIMMY: "My bracket's totally busted. How's your bracket doing?"
SARAH: "Oh, thanks for asking. Bracket's good. You know, he's gonna be six this month."
Yes, that was Sarah Palin. The former governor of Alaska was poking fun at herself -- she joked that she had a kid named Bracket, which wouldn't be too far off from the unique names she's given her own children: Bristol, Trig, Track, Piper, and Willow.
Sarah seemingly agreed to the bit to promote her new reality show, "Amazing America," which is all about the hunting and fishing lifestyle, set to air on the Sportsman Channel.
The cable network has ordered 12 episodes, kicking off with the April 3 series premiere. The program follows Palin's previous outdoors-driven series, TLC's "Sarah Palin's Alaska." It aired in 2010.
