William Shatner has already made his bones by offering dramatic renditions of Sarah Palin's tweets on the "Tonight Show with Conan O'Brien" Recently, he turned his attention to one of Palin's biggest critics, former almost-son-in-law, Levi Johnston.

Johnston's tweeted response: "WELL DONE MY FRIEND...... WELL DONE !!!! I TIP MY HAT TO YOU, THE GREAT WILLIAM SHATNER, IF ANYONE, IM GLAD IT WAS YOU :) "

Problem was, the Twitter page from which the Tonight Show pulled Shatner's material was not, in fact, Johnston's, but that of an imposter. (Later in the day, the page's creator all but admitted that it was a hoax, and had been for some time -- despite the fact that Shatner's reading was just the latest in a long line of media attention it has received.)

O'Brien's response when he found out he'd been had: He brought Shatner back to read some of Johnston's legitimate posts.
