In the 17th Century, left-wing puritans would frequently find themselves before magistrates for disrupting church services, refusing to pay tithes, and otherwise resisting the public order. Then they would dig deeper holes for themselves by addressing the judge with the egalitarian "thee" instead of the respectful "you." It is perhaps in this spirit that Steven Edholm, the originator of today's apple, informs me that the correct spelling is, all caps, " BITE ME !" including an obligatory exclamation point.
