Trivia: There's Something About Mary
- AFIS 100 Years 100 Laughs: #27
- Enforced Method Acting: Ben Stiller's stretcher really was dropped as he was taken to the ambulance.
- Fake American: Brit Lee Evans as Norm, who in turn invokes Fake Brit.
- Hey, It's That Guy!:
- Star-Making Role: Cameron Diaz and Ben Stiller became bankable leads after the runaway success of this film.
- What Could Have Been: The film's original ending had Ted getting hit by a bus right after Mary chooses him over her other suitors (basically turning the film into a Shoot the Shaggy Dog story). The Farrelly Brothers decided this would be too dark of a way to end the film, so they went with a more traditional happy ending.
