The April Fool tradition is a time-honored one, and observed in many places around the world. Although its exact origins are unclear, in part it is thought that the celebration coincides with the beginning of the new year (which is April 1 by pre-Gregorian reckoning).

On this week's edition of At Water's Edge, we celebrate -- albeit a day late (and a dollar short) -- the tradition of prank and humor with a program devoted to foolery of all sorts.
