As a kid: peanut-butter and pepperoni sandwiches, or on a tortilla
Also, I know quite a few people who at Wendy's will get a small frosty to dip their fries in. I've tried it, and it's pretty good.
In college I ran across a group who puts honey on their buttered popcorn.
Cooked rice + cinnamon and sugar + milk = incredibly good cereal on an upset stomach
Today, for breakfast, I put honey on my store-brand honey-bunches-of-oats because I didn't find it sweet enough the other day. It worked, so I'm going to be doing that.
Honey covered rice crispies
Mix melted chocolate and peanut butter, pour over cheerios, and stick it in the fridge overnight.
I can't eat scrambled eggs without adding the following before cooking: a bit of milk, some shredded cheese (mozzarella is a must, sometimes a bit of cheddar too), salt and pepper
Common in Canada, but I'm not a Canadian so weird for my area:
brown sugar and peanut butter sandwich
Putin (fries with gravy and swiss cheese, about the only thing I like swiss cheese with)
Adarondak Sandwich (peanut butter, brown sugar, bananas, toasted in the oven)
Bananas, milk, and brown sugar. (that's really all it is, though technically, it's only one sliced-up banana)
My brother used to put ketchup on everything. The weirdest was ketchup toast. I think he once put it on a peanut butter sandwich. I couldn't touch ketchup for a couple years after watching what he did with it

With how much I add brown sugar and honey to everything, I'm surprised I didn't get more curvy sooner O.O
