Every day is April Fools' Day. Pure heaven for the prankster, Pranklopedia is as indispensable a compilation of pranks as Jokelopedia is a collection of jokes.

Written by longtime Nickelodeon Magazine editor in chief Julie Winterbottom, Pranklopedia is a complete prank encyclopedia. It includes over 70 pranks, with step-by-step directions; a full-color, sixteen-page insert of supplementary materials, including "tasty " soup can labels (mmm, Cream of Sparrow Soup! ) and a "winning " lottery ticket; recipes for such essential prank-stuff as fake snot, fake vomit, fake ice cream; tips on how to pull the perfect prank; profiles of famous pranks and pranksters; even a prank woven right into the book-spot the fake entries in the Prankster Hall of Fame.

As for the pranks themselves-they're priceless. Classics like short sheeting the bed and the dancing dollar. There's the crude-mouse turds in ice-and really crude-make fake, edible dog poop. And there are pranks especially good to pull on your parents- deliver the "Take Your Teacher Home Day " letter from school and watch them freak out.

One word of caution: Use common sense in deciding how often to use Pranklopedia, or you might find yourself looking for a new place to live.
