I do remember the "Zacks of All Trades" PSA as part of the ABC Saturday Morning schedule during the mid or late 1980's. The segment on "Zacks of All Trades" was Jack & Jill (not as part of Mother Goose's nursery rhyme). There are three Zacks PSA during the ABC Saturday morning staple "The Blob" and "The Name Game" (based on a Shirley Ellis song from the 1960's). Love to hear that opening jingle "Don't pout, check it out! Zacks gonna show you what work about!". I remember that motto when I was a kid.

Quaid (looking at Hauser a.k.a. himself): No shit.
