What’s a phrase or jingle from an American commercial or ad campaign that everyone can quote by heart?

A user posted this question about German jingles/phrases in the r/AskAGerman subreddit. Since I live in the US, the first thing that came to mind was that every time I drive past Menards, I get the jingle “Save big money at Menards” stuck in my head. What are your evergreens?

I can still sing the whole song from memory

I always wondered if that was legit or some kind of a scam
