This poster is part of a new series of ads put together by the Liga Contra el Cancer in Peru, urging men to play with their balls more often in an effort to help stop testicular cancer.

Not that many men will need the encouragement, but the "give your fingers a better use" motif is a catchy one. Maybe not as catchy as the pink undies, but catchy.

So, yes. Male readers, put down those controllers and give yourself a feel. It's for a good cause!
