Jerry Seinfeld has some advice for Conan O'Brien: don't even think about complaining, big guy. The man that made NBC "must-see" in the roaring Nineties said the newbie 'Tonight Show' host hasn't been held back by the peacock network, which announced over the weekend it will be bringing Jay Leno back to 11:35.

"What did the network do to Conan?" Seinfeld asked at the TV Critics Association on Sunday. "I don't think anyone's preventing people from watching Conan. Once they give you the cameras, it's on you. I can't blame NBC for having to move things around. I hope Conan stays, I think he's terrific. But there's no rules in show business, there's no refs."
