Conan O'Brien thinks that just because he's the host of the "Tonight Show," he's famous. (We'll see about that.) He's trying to cash in on his "celebrity" by manufacturing scandalous moments and selling the pictures to the press. Last week he pretended to mow down a Bible salesman. (It looked so convincing, we got the feeling he's had some experience in that department.) This week, he took some bras and panties he happened to have lying around and pretended to sneak out of Barbara Walters's trailer with them. Note to Conan: Babs would never have you.
