Guide Note American television actor Donny Most played the role of "Ralph Malph", the class clown on the hit television series Happy Days from 1974 to 1980.

Most first developed his love for acting as a third grade student when he saw The Jolson Story. At 15 years old, he performed in New York's Catskill Mountains and and quickly started professional acting classes and appearing in television commercials.

He auditioned for the part of "Potsie" on Happy Days, and was rejected due to his red hair. The production team already had their red headed star with Ron Howard, and the role he wanted of "Potsie" was Ron's best friend. The character "Ralph Malph" was changed from a dumb football jock to a class clown to use more of Most's comic ability as the producers loved him and wanted him on the show.

After the Happy Days finale, Most expanded his career to voice over acting for weekend cartoons such as Fonz and the Happy Days Gang; Teen Wolf, Dungeons & Dragons.
