From The New Yorker (published November 24, 2003):
Article XII of the 1663 Jamestown Convention has been amended as of this date to include the following:
1. Thanksgiving-dinner guests are no longer required to play Scrabble, Go Fish, or Monopoly with children under the age of ten. Withholding of liquor is coercion.
9. Reminiscences that touch upon parental favoritism, unpaid personal loans, and arrests of blood relations’ children are discouraged.
10. You are entitled to ten naps per twelve-hour Thanksgiving Day period. Moments after 4 p.m., when time itself seems to have stopped, do not count as naps. Do not commence a nap when a blood relation older than you is addressing you directly.
There’s several more.
