Bob should start a topic called "This Week in Hilary". He could update us all once a week with the latest Hilary news, and each update he gives us another reason why Hilary is better than Lindsay Lohan. Also included, of couse, is Bob's Fashion Corner. Each entry would be signed "I am NOT obsessed! Sicerely, Bob Barron". Of course, Mole would have to write the counter piece. "The Lovely Lindsay" would cover everything from film news and music reviews to why his eybrow piercing ISN'T incredibly gay. Then, once a month, the board hosts a Crossfire-like discussion thread where the two superfans trade insults about the other's type of woman. This occurs, obviously, while almost totally avoiding the topic that week.
It's too bad that doing this would interfere with Bob's schoolwork(wourk?) though. A shame, really.
