Best a/V sync

I spent a part of my early career negotiating sync licenses. Last week I was impressed with “Smoke”’s use of “March of the Pigs” after Egeron’s character (Gudson) felt betrayed by Kinnear’s characters (“Englehart”) betrayal after he got sucker punched in the bar and while he set the string of smiley faced fires. What are some of your favorite and memorable music syncs with A/V in movies and TV?
