Worthington's commercials were seen on every television channel in Los Angeles throughout the 1960s and early 1970s, mostly through saturation advertising during the overnight hours. The commercials would be accompanied by a jingle set to the tune of If You're Happy and You Know It, with the lyrics re-written to the refrain of "If you want a car or truck, go see Cal, if you want to save a buck, go see Cal;" following this were several different versions of the lyrics, such as "Give a new car to your wife, she will love you all your life" or "I will stand upon my head until my ears are turning red," and ending with "Go see Cal, Go see Cal, Go see Cal". When the idea of a jingle was first pitched to him, it was conceptualized as slow with a big roll up of drums; Worthington disagreed and felt the song should be fast and wrote the lyrics and recorded the song himself (along with local friend country western singer songwriter Sammy Masters). The jingle was successful. In the years following, Worthington discovered that there were children who thought that his name was "Go see Cal." Others managed to mondegreen as "Pussycow."
