This is from a humorous section in a newspaper, close to 200 years ago! I think it does have some basis in fact as the philosopher Jeremy Bentham did very much march to his own drummer.
“ . . . Mr. Bentham, author of the “Panopticon,” and sundry other light and amusing books, never sits at the table above a certain number of minutes; when the proper time has elapsed, he rises up, walks out into the middle of the room, and, clasping his hands together behind his back, ducks his head down several times, and runs around the room, repeating without ceasing, the same operation; and this he calls
performing a vibration.”
