Interestingly, just as we on HW can't type certain strings of letters without getting "censored" by the program, Shakespeare did virtually the same thing in some of his plays. In Twelfth Night, for example, the character Malvolio finds a letter supposedly written by the object of his affection and says, "By my life, this is my lady's hand: these be her very C's, her U's and her T's
and thus makes she her great P's."
Even modern audiences, with their minds in the gutter, find these lines amusing, adding the missing letter between the "u" and the "t."
(Yeah...I was an English major).
