Anthony Jeselnik was a last-minute addition to last night's Late Night with Jimmy Fallon, and in doing so, became the first stand-up to perform on the show. Comedy trivia! Of course, Fallon's people knew Jeselnik was available, since he's a writer on the show, and he already has performed in front of the camera in a couple of sketches in the first month. If you've seen Jeselnik's half-hour Comedy Central Presents or his appearance on HBO's Down and Dirty with Jim Norton, you know what you're in for. Jeselnik said that three of his jokes got cut for time. What impressed me the most, however, was his opening line. Such a bold thing to say and yet it fits right in with his stand-up persona.
