Sheep lamb fries—are considered a delicacy in many parts of the world. Perhaps the most unusual dish of sheep meat is the Scottish haggis, composed of various sheep innards cooked along with oatmeal and chopped onions inside its stomach. In comparison, countries such as the U.S. consume only a pound or less (under 0.5 kg), with Americans eating 50 pounds (22 kg) of pork and 65 pounds (29 kg) of beef. In addition, such countries rarely eat mutton, and may favor the more expensive cuts of lamb: mostly lamb chops and leg of lamb. Though sheep's milk may be drunk rarely
1/3–2/3 conjecture unsolved; call it "one of the most intriguing problems in the combinatorial theory of posets." A survey of the conjecture is given by . The 1/3–2/3 conjecture is known to be true for certain special classes of partial orders, including partial orders of width two, partial orders of height two, partial orders with at most 11 elements, partial orders in which each element is incomparable to at most six others, series-parallel partial orders, and semiorders. In the limit as "n" goes to infinity, the proportion of "n"-element partial orders that obey the 1/3–2/3 conjecture approaches 100%. proposed the following application
