YOU THOUGHT WRONG!
I can show you how to make an absolutly PERFECT s'more, possibly useful for world domination. Then again, maybe not. You'll just have to try it and find out!
Step 1: Step 1: Find Various Bits
2 Graham Crackers
4 Big Chocolate Chips, I like Hershey's Mini Kisses
Step 2: Step Two: Prepare the Super High Tech Marshmallow/Chocolate Module
After that, put the other two chocolate chips on each side of the marshmallow (Picture 2).
Put the whole thing on a graham wafer so that it doesn't tip over (Picture 3).
Step 3: Now this is the (comparitively) hard part....
First put the graham wafer/marshmallow/chocolate unit in the very center of the microwave. Close the door, set it for 10 seconds, and DO NOT PRESS START YET. What we're trying to do here is press the 'stop' button just as the marshmallow begins to swell up significantly. I generally wait for it to either start to spill over the edge of the cracker, or a chocolate chip to fall out. It may not work very well the first time.
Go ahead and do that, and the marshmallow will immediately begin to deflate upon removal from microwave, ending up something like the one in the picture. Notice that a chocolate chip has been pushed out; make sure that all chocolate chips are in contact with lots of marshmallow. The chocolate chips themselves don't seem to be affected by the microwave, so it's the heat of the marshmallow that softens the chocolate.
