1976-78 Commercials: Pre-Heat, Cat Chow, Playtex, Levi's, ABC, Nestle Crunch

That's veteran New York actor/voice-over Mort Marshall (the original voice of the "Trix Rabbit", "Stanley Livingston" in "TENNESSEE TUXEDO AND HIS TALES" and "Klondike Kat" on "THE UNDERDOG SHOW") in the "Purina Cat Chow" ad. Playtex was always "modest" about showing off their various bras in their '60s, '70s and '80s ads [usually via mannequins]; it wasn't until the '90s, though, when live models were demonstrating them on their own.

I was probably out of the country at the time and don't remember: Wasn't "Fonzie Loves Pinky" a "Happy Days" storyline and not a spinoff of its own?

You are correct. Fonzie Loves Pinky was a three-part episode shown after the regular episode of Happy Days in September 1976. This is pretty much the main reason why Happy Days was number 1 in the A.C. Nielsen Ratings in 1976-77. This was my second favorite show growing up (second to Laverne & Shirley, Happy Days' first spin-off)

Thanks for the info. Wasn't in the country at the time, so I learned something!

Great round of new posts, by the way.
