Crest Toothpaste (commercial, 1960s)

A lot of people think of Bill Cosby, but I'm really tooth decay. I'm tooth decay, but I'm actually on vacation, especially with the teeth I've been working with here. Mainly because some wise guy has been brushing after every meal, and I think the thing that hurts me the most is the fact that he's using crest.

Yeah, see, Crest has fluoride. See, makes teeth hard, the enamel. You can't get in, you hit, you hit, you hit, and the only thing left for me to do is just wait for a mistake.

And when I get that mistake, I'm going to tear into it. Here it comes again right after the meal. Gonna get another little bath. Fighting cavities is the whole idea behind Crest. .
