This is starting to become a trend at NBC. First Conan whacked his head after slipping on the stage during a sketch, and now Jay Leno hit his head during rehearsal for a stunt. Luckily Leno's injury wasn't bad enough to send him to the hospital like Conan's was.

Of course, this injury gave Leno an opening for a Letterman joke.

Producers over Warner Bros. sent us a press release announcing a pretty cool/unprecedented web extra from the comedy,The Class. Next week, they're going to do two live webcasts of rehearsals.

The first webcast is The Table Read on Monday, January 15th at 11 am (Pacific). You'll get to peek in as the cast gives a first reading (literally around a table) of that week's script. The next live webcast is the following Wednesday a 1 pm (Pacific) when the cast will do a run-thru of the script with all the changes made since Monday. This is an event that usually doesn't have an audience, so it will be pretty cool to see. Of course, it sort-of ruins the episode for you since you know what is going to happen. I suppose it will be interesting to see the final product when it airs.

Saturday Night Live may put its Friday night rehearsals on the internet. Right now, the rehearsals can only be seen by NBC employees on closed-circuit television at Rockefeller Center. This revelation came from NBC Universal chief digital officer George Kliavkoff when he spoke at a conference in Los Angeles yesterday. Kliavkoff said of the Friday dress rehearsal, "Sometimes it's more interesting than the show." He says he was only joking, but there may also be a little truth to what he said. Not sure how SNL executive producer Lorne Michaels feels about Kliavkoff spilling the beans about something he is simply mulling over.

While you'd think I would be on behind-the-scenes overload for sketch comedy shows, since I watch both 30 Rock and Studio 60, I'd actually be curious to see the Friday rehearsals. It would be interesting to see which sketches make it and what changes are made to them before the live show. I guess the down side would be that SNL is giving away its sketches ahead of time. We could view the Friday rehearsal and decide whether SNL is even worth watching the next night. Although, at this point, I just always assume it's not worth watching.
