The Grocery List.  The most common known list known throughout the world.  Every man screws it up and every woman becomes  a five star general.   Myself, I fall in neither sexist category because I refuse to buy food solely for one purpose, whether that be solely to save money, to ensure I obtain all the ingredients for my grilled cheese sandwich, or to obtain more coupons for that next coupon shopping extravagenza that people devout their lives to.
