I have still never seen Talented Mr. Ripley, which I keep knowing is a mistake on my part :P

But oh yes, Cory and Shawn. Totally, totally preteen boyfriends. Or at least a long-running joke on the part of the actors and writers at the audience's expense. And then later on there was the intense boyfriendyness of... Will Fridel and Matt Laurence? I don't remember their characters' names. That show was all about the MMF OT3 ships.
