Growing up with TV, there were many commercials that I looked forward to. Probably too many to name and too many I've stuffed away in some corner of my memory.
The ones that pop to mind are the Charmin commercials with Mr. Whipple, the Chuck Wagon commercials with the dog running after the wagon, the Slinky ads, Madge with her Palmolive, Mrs. Olson with Folgers.
I remember the Duncan yo-yo ads, the K-Tel records ads with every known song, or the ones with the English actor John Williams for the Treasury of Classical Music. I can still hear his enunciation, ". . . that was Polovtsian Dance number three by Borodin."
My favorites were the local NY area commercials. Billy Crystal would make fun of local host Joe Franklin (who always looked old even when he was young, so I was surprised that he was alive a few years ago, now he's not, but he was entertaining). Franklin had a really, really late or really, really early talk show on WWOR channel 9 that I shouldn't have stayed up for, but it was worth it. Billy Crystal's affectionate poke fun at Franklin was spot on. Which leads me to Franklin's two main sponsors:
Martin's Paints ("If it ain't Martin's, it ain't paint") and matzohs by Streit's, which he would plug many times coming in from and out to commercial.
