Thinking back to Waterboy. Strange movie, because he's technically the lead... But in reality, he's just supporting other people's comedy. Like, all the funniest moments are things that other actors do. And it's not even like he's playing the straight man that occasionally has jokes, like Harrold Ramis in Ghostbusters. He's definitely being funny throughout the movie... It's just that all the best lines and acts went to the "supporting" cast. I'd like to think that's deliberate, and give him credit for the unique style.
