Content:  The four teenage lead characters of Scooby-Doo were inspired by four of the main characters from the 1959–63 American sitcom The Many Loves of Dobie Gillis, with Shaggy having been derived from the character Maynard G.

Maynard's beatnik-style goatee, general appearance, and use of the word "like" all found their way into the character of Shaggy, with the base personality of the character updated to make him a hippie rather than a beatnik. Casey Kasem, the first voice actor for Shaggy, said that he originally felt uncomfortable after being assigned to Shaggy. Kasem stated that while he was "hip to what hippies were about", he had never before portrayed a hippie character.
