Here is what you need:
semi-sweet chocolate chips
graham crackers
marshmallows (big!)
foil-lined pan
Preheat your oven to 350 degrees. Line pan with foil and line with graham crackers - it could be one or lots - I needed 2 to stomach Spence (and Justin Bobby.) Cover graham crackers with chocolate chips.
Like this:

Then you pop them into the oven to melt the chocolate chips a little bit. Keep in mind that chocolate chips are designed to hold their shape - even when melted. I'd take them out after 3 or 4 minutes.
Place a marshmallow on top of the melted chips, like this:

Put the pan back into the oven for 3 or 4 minutes more - the marshmallow will puff up and you will know when to pull them out.
I like mine like this:

You can eat them like that - or do what I do - and smoosh them a little for extra ooey gooey-ness.

After eating 2 of these, Spencer and Justin Bobby almost seemed like regular guys. I always knew chocolate could fix anything!
