Pop star Justin Bieber made his SNL debut on February 9 by pulling double-duty as host and musical guest of the late-night comedy showcase. For one sketch, the Biebs and cast members performed a parody of the musical Grease, which poked fun at Bieber’s baby-faced swag and his ability to make ladies of all ages melt. Spoofing the musical's "Summer Nights" number, Bieber plays an 11-year-old "Greaser" trying to woo Cecily Strong and impress his buddies. However, he’s confused by car doors and surprised that "sweater puppies" aren’t actual puppies. Check out the hilarious skit below!
