The plot is this dude goes out to pick up food and while he's gone his gf tries to hook up with his friend. The friend keeps trying to talk her down but she is persistent. Eventually he tells her that he loves men. "I had a Eureka moment and realized that I love men." She doubts him majorly and when the friend comes home she tells him to tell his buddy that he loves men and he does. The friend says, "I always suspected it! What's more, I always knew!"
