Life and careerEdit
Born in Brooklyn, New York, Don lived in Flatbush, Brooklyn, New York, and graduated from Erasmus Hall High School in 1970. He attended Lehigh University for three years from 1970 to 1973, but did not graduate. Originally intending to study engineering, he changed his major to business after his first semester. He made plans during his junior year to spend the summer of 1973 in search of acting jobs in Hollywood before completing his studies at Lehigh. Instead, he landed the Ralph Malph role on his third audition and moved to California to pursue acting full-time. 
Don has appeared in other film and television work. Film credits include the Ron Howard directed EDtv (1999), Planting Melvin (2005) and The Great Buck Howard (2008). He also made the regular round of guest appearances on TV shows like Emergency!, CHiPs, Baywatch, The Love Boat, Sliders, Star Trek: Voyager, Diagnosis: Murder and Glee. He also made an appearance on Charles in Charge, alongside his former Happy Days co-star, Scott Baio. He plays a man who has just won the lottery, and as part of the cameo joke, runs up to Scott Baio and waving the winning ticket shouts, "It looks like Happy Days are here again!" He also receives several looks from Scott Baio that suggests familiarity throughout the episode. He is sometimes credited as "Donny Most."
As of 2017, Most is performing in a U.S. tour, "Donny Most Sings and Swings," performing a set of 1950s swing music with a 7-piece backing band.
