Scott Baio got his first major role as Fonzie's tough cousin, Charles 'Chachi' Arcola, at 16 on the then already popular television show Happy Days. In 1982 he starred in a spin-off of Happy Days entitled Joanie Loves Chachi, which lasted only one season. That same year he appeared opposite future Charles in Charge costar Willie Aames in the film Zapped!, the story of a boy who obtains telekinesis and subsequently uses it to "zap" the clothing off of attractive females.
Baio made his first album for RCA in 1982, self titled, it featured songs including: "What was in that Kiss", "How Do You Talk to Girls", and "Wanted for Love". He released a second album for RCA entitled The Boys Are Out Tonight. He was a teen idol featured in teen magazines, often with no shirt on.
In 1984, after Happy Days ended, Baio starred as a nanny on Charles in Charge, a show which lasted until 1990.
Since the end of Charles in Charge, Baio has appeared in other short lived sitcoms, including Rewind which was picked up by the Fox network in 1998, but cancelled before any episodes aired. He appeared in the 2003 film A Wedding for Bella.
In 1997, it was rumored that he had died in a car accident, but this was proven false. The source of the rumor is unknown.
He has dated Erin Moran, Pamela Anderson, Erika Eleniak, Nicole Eggert, Natalie Raitano, Nicolette Sheridan, Brooke Shields, and Heather Locklear. His success with women led to his induction into The Man Show Hall of Fame on July 21, 1999.
He is also subject of one of the Rarest and most prestious items in the Kingdom of Loathing. An honour bestowed upon very few.
