Scotty, Scotto, Scooter. (Okay, that last one is made up.)
Famous people named Scott:
TV personality Scott Disick; actors Scott Baio, Scott Wolf, Scott Bakula, Scott Speedman, and Scott Wilson; novelist F. Scott Fitzgerald; composer Scott Joplin; figure skater Scott Hamilton; rapper Scott Ramon Seguro Mescudi (a.k.a. Kid Cudi).
American poet Francis Scott Key wrote “The Star-Spangled Banner.” I bet his parents called him Scooter.
