Every cartoon needs conflict. The small micro just wants to have a pleasant morning watching cartoons with a snack. Of course, there's always some ass waiting to spoil your fun, literally in this case. Whether the macro knew he was there or not, he ain't getting up, crushing the poor micro beneath him.
Of course, no cartoon is complete without a butt poke, and the micro takes advantage of the pin close at hand. No matter how big you are, getting a needle stuck in your butt is not a pleasant feeling, and the macro is not too happy...
