Mad Clown is a traveling circus clown who decided to take up boxing. He made his only appearance in the SNES version of Super Punch-Out!! as the third boxer in the World Circuit. According to the manual, Mad Clown was originally an Italian opera singer. After having a nervous breakdown, he abandoned his singing career to join the circus. The monotony of performing the same juggling routines night after night, combined with being forced to drive a car that was much too small, prompted him to take up boxing. He is a reference to Pagliaccio, the lead character in the opera Pagliacci by Ruggero Leoncavallo.
