Michael Cera, Late Show, David Letterman, Letterman
If you're like us and value your sleep, you probably nodded off into your Ambien dreamland before the party started on post-prime time TV. Don't worry; we've got you covered. Here's the best of what happened last night on late night.

"The Late Show" was the only late night program not in repeats this week, and featured guest Michael Cera, there to promote his Broadway run in the play "This Is Our Youth." Cera chatted with host David Letterman about a recent road trip he took with his girlfriend, a German citizen who had never been to the U.S. before. The pair stopped to see the world's largest basket, a basket-shaped office building in Ohio, though the actor admitted that his girlfriend "didn't care for it." Letterman was bemused by that revelation, though he was downright annoyed that the woman apparently didn't like Cracker Barrel, either.

Cera also shared an anecdote about a prank he pulled at the Sundance Film Festival, in which he planted a friend in the audience during a Q&A session following a screening of his film "Crystal Fairy." The friend was told to ask a nonsensical question about Cera's illegitimate son (who does not exist, the actor clarified), and did so. The audience, however, didn't get -- or like -- the joke, and neither did Letterman, who declared that Cera should be banned from Sundance for his shenanigans.

Letterman also featured another installment of his ongoing Dock Diving Dogs series, in which canines run and leap into a giant pool of water, competing to see who can jump the farthest. A trio of pooches participated, getting some impressive air and landing some long lengths, including one that was predicted almost exactly by Cera. "I never knew I could do that," the actor marveled.

Lyle Lovett was the musical guest, and sat down with Dave to discuss his love of horses, and his participation in reining competitions, which show off the skills of quarter horses traditionally used on ranches. "The Late Show" dug up a video of one of Lovett's competitions, and his horse, Smart and Shiny, performed some impressive tricks, including coming to a complete stop from a run and turning in tight, fast circles. Letterman joked that the animal would be the next competitor in the Dock Diving challenge.
