Here's some more about it; one of the the Washington Post's Style Invitational contests asked readers to submit "instructions" for something (anything), written in the style of a famous person. The popular winning entry was "The Hokey Pokey as written by William Shakespeare":

The Hoke, the poke -- banish now thy doubt
Verily, I say, 'tis what it's all about.
