Here's a fun animated commercial from the early 1980s. It's Cookie Jarvis, the wizard, and the Cookie Crook promoting Ralston-Purina's Cookie Crisp cereal. Ah, cookies for breakfast...!
Feel free to post a comment and share your memories of Cookie Crisp cereal. I ate this a few times, but cookie cereal just wasn't right for me. But I did enjoy old Cookie Jarvis.
