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 the language of probability theory. One may define a uniform probability distribution on the linear extensions in which each possible linear extension is equally likely to be chosen. The 1/3–2/3 conjecture states that, under this probability distribution, there exists a pair of elements "x" and "y" such that the probability that "x" is earlier than "y" in a random linear extension is between 1/3 and 2/3. The 1/3–2/3 conjecture was formulated by , and later made independently by Michael Fredman and by . It was listed as a featured unsolved problem at the founding of the journal "Order", and remains
