Mark Paul Gosselar, who stars in Raising the Bar, appeared on Jimmy Fallon in character as Zack Morris from Saved by the Bell.

The Monday episode of the Martha Stewart show will be "entirely dedicated to the world of pot." An email today from the show said:

Monday’s episode will feature Martha talking about her stash of pots while an onscreen crawl highlights every word she uses that includes "pot." She’ll hang out with some pot-bellied pigs, chat with some professional plant potters, and welcome guest Jimmy Fallon, who brings Martha a plate of brownies upon entrance (while cracking an already-tired Michael Phelps joke) and later cooks his favorite chili in, yep, a Crock-Pot.

Martha is finally putting her prison skills to good use.

Jimmy Fallon was on the Tonight Show with Jay Leno promoting his webisodes, as well as the premier of Late Night with Jimmy Fallon, which starts in March.

Jimmy asked Jay how to deal with interferring networks. That’s when Jay threw a cup of water on him.

Was it staged, or is Jay feeling a little hostility?

Jimmy Fallon is set to replace Conan O’Brien on Late Night, and O’Brien will replace Jay Leno on the Tonight Show. To garner more interest, NBC will debut Fallon line several months before the show starts.

NBC tried to retain Leno, but he said he’ll find a job elsewhere. It doesn’t appear Leno, who is the king of late night television, was ready to retire. NBC has made a lot of bad business decisions, so we’ll have to wait and see how Fallon and O’Brien do.

Jimmy Fallon will be officially named as the new host of Late Night when Conan O’Brien takes over the Tonight Show after Jay Leno steps down. A news conference is planned for Monday to make the announcement.

Fallon is a funny guy, but I still can’t see him succeeding as a late night host. Surprise me Fallon!
