Moyer "Sonny" Bupp was the prankster who gets Alfalfa Switzer to change places with him in the hospital for a tonsilectomy. He possibly got the idea from Lewis De Vore who did the exact same stunt. Sonny also appears in Our Gang Follies Of 1936. He has a brother, Tommy Bupp, who drops from his treehouse in Hi'-Neighbor! in order to meet Percy.
Sonny and Tommy were played by actors Moyer and Tommy Bupp.
