Harry Styles pulled double duty on Saturday night as both the host and the musical performer on Saturday Night Live. During his monologue, he sat at a piano and "introduced" himself as once being in a band called One Direction. He teased the audience by saying wouldn't it be crazy if they were here? Then he would pause and look around as if they were going to come out on stage. Of course they didn't come out. Then he said, "they're my brothers. Niall, Louis, Liam and uh...Ringo." No word on whether Zayn Malik found the humor in that .
