Brett Favre in There's Something About Mary (1998)
Director: Peter Farrelly
To prove that everyone does, in fact, have something for Mary, she even woos a famous Greenbay Packers quarterback, Brett Favre. As Mary's former lover, Favre is pretty convincing despite not having an acting credit to his name. And in case you're wondering what he's doing there, showing up in Mary's life again, he's there to "play the Dolphins, you dumbass."
