What's a food combination that goes surprisingly well together?

Milkshake with crispy bacon. You've got sweet, fatty, salty, crunchy, umami, creamy. So amazing. Blend or crumble a couple pieces into it but then have a whole piece or two stuck in it so you have bigger pieces to play around with. Has no business being as good as it is

In college we used to take a Ritz cracker, ez cheese, and top with a pizza roll. I haven't tried one in some years now but I remember it slapped at the time

Used to know someone who would pour a box of junior mints into popcorn at the theater. Shake it a couple times, let it sit just long enough to get a little melty, then go wild. Bonus points for adding enough buttery topping to soak through the bottom of the container
