All the tube news that’s fit to surf (in this incredibly slow TV news week) …

– Broadway and 30 Rock star Cheyenne Jackson will be making a guest appearance on the next season of Curb Your Enthusiasm, which is filming in New York City this summer.

– Lord of the Rings star Elijah Wood is heading to the tube, for the first time, in an odd new FX comedy.

– Potential Larry King replacements: Ryan Seacrest, Piers Morgan and … Joy Behar? No, CNN. Just no.

– The new season of Weeds, which kicks off in August, will find Nancy Botwin and her family on the lam, in a Winnebago.

– Is The Big O ending her daily talk show just in time? Because her ratings are down. Way down.

– Craig Kilborn also didn’t grab such hot ratings in his return to TV on Monday.

– Eminem and Christina Aguilera will guest star on the season finale of Entourage, which is also suffering from a ratings downturn: The season premiere last Sunday was down 26 percent vs. the previous season’s premiere.

– Coming soon to a network near you: Susan Sarandon‘s ping pong reality show. For reals.

– All those people who were on the receiving end of Gordon Ramsay‘s sometimes harsh criticisms on Kitchen Nightmares might not be feeling a lot of sympathy for the chef, who had to close down one of his own eateries in London.

– This is a buzzkill: Starz has canceled Party Down, one of the funniest shows on cable.

– And check out big-screen (and Freaks and Geeks) star James Franco‘s goofy return to his General Hospital guest stint today, including the monkey toy that I’m assuming is a little shout out to the James Dean toy monkey scene in Rebel Without a Cause, since Franco played Dean in a TNT biopic. If not, it’s a really cool coincidence, no?
