The episode was in one of the latter seasons,

Cole was coming out of the shower in naught but a towel and Dylan some how manages to trick him into going into the coridor and rips the towel away from him before locking him out. Leaving him, supposedly, naked in the corridor; though of course we don't see anything below the waist on the screen.

I watched a movie once, can't remember what it was called now, it was a non-english film and it featured a boy lead. During the film there were no semi clothed scenes at all... but then as the credits were rolling the boy (for no reason that connected with the story at all) goes up the local river for a swim, strips down to his little bathing shorts and jumps in and there, underwater, waves to the audience. WHY? Why this semi-naked acknowledgement that he's being watched?

Am I just reading into it?

Who knows?
