I'm remembering a commercial, I'm pretty sure TV Land aired it as a retromercial back in the 1990s, it has a father talking to his son about how he's doing poorly in math. The son points out better grades he got in other classes, the father remarks "yeah, but you've got to do good at math", and I think the boy also points out he didn't have any cavities or something.
And while we're on the subject of old commercials that aired as retromercials, and I'm sure I have seen it on YouTube in the past but now am having trouble finding it, there was a commercial with a woman I a sexy dress driving a car, I think to the beach, at the end she takes off her dress, showing her in her bikini, and when the logo is shown at the end, an animal is shown, making a roar-type sound. I'm thinking it's either a panther or a tiger or a jaguar. I know there was music playing, though I can't remember any lyrics (if any, but I'm sure there are lyrics).
And another one was for some kind of drink. A woman, in a seductive or sensual tone, says she wants a drink, when the announcer offers something, she says "but I want a real drink."
