How funny that I just came across your post! Here I am searching the web looking for the exact same thing! It was definitely late 80s early 90s. All I remember is "Bob, Bob, Bob, He doesn't attract mosquitoes; Bob, Bob, Bob, He likes to eat Doritos."
Have you found anything yet? I would be really interested in anything you come up with, if you wouldn't mind passing it on.
> Does anyone remember a Doritos commercial from the late 80s or early 90s with a jingle that included the line "Bob Bob Bob" and something about a mosquito?
> Any help would be greatly appreciated!
