The Alvin Show was a cartoon shown in the sixties about David Seville and his singing group The Chipmunks, literally comprised of actual chipmunks (puppets in the original show). The three Munks consisted of the mischevious Alvin, the gluttonous and shy Theodore, and the ingenious Simon. The Chipmunks were always getting into trouble, with Dave yelling "AAAAAAALVIIIIIIIIIIN!" when he found out.
An updated series simply titled Alvin and the Chipmunks was created in the eighties.
Several films have been made in recent years, with mixed reviews at best.
