Name: Rowlf the Dog
First Appearance: Purina Dog Chow commercials (1962)
Description: He may have been created for such an insincere purpose as advertising, but darn it if he isn't lovable! He's light-hearted and silly (but not to a fault), and can be found playing the piano most of the time. Rowlf spent a lot of time on The Jimmy Dean Show, being the first muppet to be considered famous.
