I actually remember this, back when Nickelodeon kid actors weren't trying so hard to be funny. Or maybe I'm just prejudiced because I'm not a kid anymore.
When I saw the title for this in the hopper, I immediately started singing this song, and I knew the whole thing. What the hell did nickelodeon implant in my brain as a child?
When I was a kid I would write my own commercials, but they would say something along the lines of "Welch's Grape Juice makes you puke", and all the commercials would star Nancy McKeon.
