To cap it all

There are a few monkeys (or a monkey family?) around the department where I study, and whenever I have reason to walk past them (like it happened today), I usually un-cap my head lest any of them feels tempted to do the same. Perhaps the old hatseller-vs-monkey algorithm can be used to retrieve it back, but then these are IIT monkeys (we're not talking MTech students here, of course) and there's no telling how educated they really are and what their level of folktale-awareness really is.
