Today is one of those days where we get two different holidays. It's National Banana Split Day and also National S'mores Day.
I've only had s'mores once in my life, I think (I guess that happens if you're not a boy scout). As for banana splits, I haven't had one of those in years, though I still remember the theme song to the TV show ("La La La, La La La La, La La La, La La La La"). Here's a recipe from Epicurious if you want to make the grahams and marshmallow from scratch. If you want to just use store bought food, take a look at the Honey Maid recipe. And if you want a variation, here are a million more recipes for s'mores.
These two holidays actually go together, so here's your assignment: make a banana split, and put some s'mores in it. Then go for a walk or do a sit up or something.
