I remember watching a cable broadcast of "Grease" (1978) and there's a scene where the Pink Ladies are watching TV, and a commercial comes on promoting Ipana toothpaste, featuring Bucky Beaver. I'm like, how come I've never heard of Ipana? At the time, the only toothpastes I knew came from Colgate, Proctor & Gamble (Crest), and Lever Brothers (now Unilever), which at that time put out Aim, Pepsodent, and Close-Up, all of whom have since been sold to other entities.
The same can be said of Ipana, which was a product of Bristol-Myers, better known now as a pharmaceutical retailer that no longer has any marketable items on the shelves. They divested their wide range of products, including Ipana, Bufferin, Excedrin, et al, several years back. In fact, you can't find Ipana anywhere in the US, because it's not made for American consumption anymore. It's made and sold overseas.
Digression over. Let's take a look at a sample Ipana commercial with Bucky Beaver.
Actor-singer Jimmie Dodd (The Mickey Mouse Club) was the voice behind Bucky. Like, who knew?
