Ears-dropping --> eavesdropping.

Taken for granite -> for granted.

(French) Sans-blanc -> semblant.

Oh, movie line? Idk

France is bacon… Just kidding. Not exactly mishearing, but I misunderstood “the best defense is a good offense” as if you defend super well, you’d attack your opponent with your defense. It didn’t make much sense until I realized you’re supposed to attack in order to defend…

Can’t think of a specific line, but I’m sure something from Grease. I was obsessed with that movie as a kid, and my many questions about some of the plots and lines led to my parents giving me The Talk. So I imagine I misheard a bunch of lines about periods and such.
