Except it had the text "When you are in deep trouble, just keep your head down and act like you know what you're doing". It's a very obvious photoshop, but I like the message. It's how I learnt to be sociable, after all. Learn the rules, follow the rules, and then subvert the rules when the need arises.
One could take the "Fox amongst Hounds" metaphor in all sorts of directions, and it's definitely less threatening than the standard "Wolf amongst Sheep" attitude. After all, Foxes and Hounds are both just different kinds predators.
