Humans (mainly men) have been drawing dicks on stuff since time began. It's basically an innate ability, like breathing or farting.
This esteemed artistic past-time has now been turned into a hilarious drawing game, appropriately titled – Draw a D*ck On It.
Players take turns to add their own phallic enhancements and funny captions to mundane illustrations, they then share their creative masterpieces with the group for judgement.
The book even comes with a sticker sheet of awards to honour particularly creative works.
