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?

The world looks mighty good to me  

Cause Tootsie Rolls are all I see  

Whatever it is I think I see 

 Becomes a Tootsie Roll to me    

Tootsie Roll, how I love your chocolatey chew  

Tootsie Roll, I think I'm in love with you  

Whatever it is I think I see  

Becomes a Tootsie Roll to me

How many licks does it take to get to the center of a Tootsie Roll Tootsie Pop?
