What you need:
Toothpicks or Lollipop sticks (or anything you can skewer your marshmallow with)
We only had left over tiny toon marshmallows (from when I made the fondant for the littles' bday cake) :), I used semi-sweet chocolate chips, and all I had to poke was toothpicks, but we needed something for dessert, had little else in the house, and I was too tired to bake (it was getting towards bedtime, but we needed dessert to watch with our evening shows :)).
What to do!
*Melt the chocolate, either in the microwave at about 20 seconds at a time stirring well in between until melted, or over a double boiler (glass bowl set over a boiling pot of water, stirring constantly).
*Crush the graham crackers. You can just toss them in a baggy, smash away, could be a good release too, and it's efficient, effective, and nice and easy clean up (tip: let the air out of the bag when you seal it, so you don't pop it sending gcracker dust everywhere - we did not find this out from personal experience, though we did have a little escape out one side :)).
*Then poke, dip dip... i.e. poke toothpick into marshmallow, dip in chocolate then in graham crackers.
Then ENJOY!!! :) Like here, when a lil scruffy Hubby tried to pick off my display S'more pop ;) and you may have noticed an extra hand in the first pic.... that was the same Hubby digging in because I wasn't preparing them fast enough yet :-).
