Well, in reality you'd likely get some points with a few votes on your original submission, and if people knew you had made it first, you'd get some "credit" (whatever that concept means when you're taking pictures that aren't yours and, as often as not, putting old jokes on them as captions). Not that people know who we are anyway with anonymous usernames.
But I'm curious. Why do you think that getting points or credit for the idea is part of the reason for making memes?
