this is how i'm going to suggest doing this.

- prepare coffee maker

- put three stale crispy crunches and three marshmallows in a pretty big coffee cup

- microwave for 33 seconds

- brew coffee while microwave is going

- dump hot coffee on microwaved gooeyness

- stir marshmallow is gone and crispy crunch is reduced to hard waver

- let sit for a while, stirring occasionally, until waver is mostly melted

- add milk

i'll try again later tonight.
