Casey Kasem can't help himself.
Casey Kasem (1932-2014) was an American radio personality and voice actor who hosted American Top 40 with Casey Kasem and supplied the voice of Shaggy Rogers in Scooby-Doo.
Kasem supplied voices for animated segments in the early seasons of Sesame Street, including the "Q for Quarter" short, the "F for Fly and Frog" short, the "B wall" cartoon, the "C clipper" cartoon, and reprised his role of Robin in Batman animated segments (having also played the role in the 1969 Filmation Batman/Superman Hour series and through the 1970s and 1980s on Hanna-Barbera's Superfriends).
In 1994, by which time he'd established himself as a radio personality, Kasem appeared in the music video "She Drives Me Crazy" as the final celebrity, repeating the song's lyrics as a monologue.
