scientific breakthrough

I know what black holes are! They are the place where one would find all the erasers that came on the pencils, all the erasers bought to replace the original erasers which were used up on the pencils, all the cute birthday favor erasers which really don't erase but just smear, and all the pink big erasers bought to keep at the homework desk. Or at least one would find them in a black hole if they hadn't erased it.
