yup, I created this meme. I know this is an old joke but I like the idea of a hard of hearing old man with an old lady. It was an old joke from way back when and I am old.
It's an old joke (see discussion above). When you're trying to make someone crack up, why not go with one of the classics! Anyway, I like to think mine's a "meta meme" -- a joke about the joke, as much as anything else. :)
