Find the Face (in the Beans)
The picture is accompanied by all sorts of inferences on your mental development depending on delay until you find the face in there, which are, hmm, lame, even though they begin with “According to recent medical evidence…”.
By the way: Yes, there really is a face in there! Once you’ve seen it, there is no doubt any more (a case of “one-shot learning”).
Hint: (Part of) it is in the logo. Need more? At the bottom.
