There are plenty of people who don't get the appeal of memes, like my Great-Aunt Nance, whose internet comprehension skills are not unlike a monkey's capacity to receive treats by solving puzzles. It's nearly impossible to explain to someone why memes are funny, and doing so would likely suck the humor out of the thing anyway. It's probably best to let the internet-illiterate cherish their ignorance and go about their lives touching grass and what not. That just means more memes for us internet-poisoned folk.
