The coffee cups stand at Target has such randomness on it, all the time; the other day I bought a yellow cup that reminded me of Lego, a pink & white gingham print cup, and a white cup with pictures of cupcakes on it. They were all single cups, no others like them. I have a theory that there is a reverse-thief who likes to come into Target with a new random cup every so often and add it to the stand.
