Haggis Agriculture stated that they were reviewing the ban on beef and lamb products, but that the ban on food containing sheep lung would remain in force. As haggis cannot be exported to the United States, it is instead made there, sometimes by Scottish companies. One such uses what is stated to be the same 150 year-old recipe and ingredients as in Scotland, except that sheep lung is not used, and the casing is always artificial. Haggis Haggis is a savoury pudding containing sheep's pluck (heart, liver, and lungs); minced with onion, oatmeal, suet, spices, and salt, mixed with stock, and
1/3–2/3 conjecture the partial order place "x" earlier than "y". The partial order formed by three elements "a", "b", and "c" with a single comparability relationship, has three linear extensions, and In all three of these extensions, "a" is earlier than "b". However, "a" is earlier than "c" in only two of them, and later than "c" in the third. Therefore, the pair of "a" and "c" have the desired property, showing that this partial order obeys the 1/3–2/3 conjecture. This example shows that the constants 1/3 and 2/3 in the conjecture are tight; if "q" is any fraction strictly between 1/3
