George Hayduke is the pen name of a prolific anonymous author of prank books.
 The name is believed to be based on the character George Washington Hayduke III, created by Edward Abbey in his 1975 book "The Monkey Wrench Gang", and 1990 book "Hayduke Lives".
 Often in collaboration with perhaps equally pseudonymous co-author M. Nelson Chunder, Hayduke has authored numerous guides to pranks and practical jokes, primarily intended for vengeance.
 Activities suggested range from the merely annoying and mischievous to the illegal and extremely dangerous.
 Hayduke's book "Get Even: The Complete Book of Dirty Tricks" was found in the locker of a man accused of the USS Iowa turret explosion, which killed 47 people.

A practical joke (also known as a prank, gag, jape or shenanigan) is a mischievous trick or joke played on someone, typically causing the victim to experience embarrassment, perplexity, confusion, or discomfort.
 Practical jokes differ from confidence tricks or hoaxes in that the victim finds out, or is let in on the joke, rather than being fooled into handing over money or other valuables.
 Practical jokes or pranks are generally lighthearted, reversible and non-permanent, and aim to make the victim feel foolish or victimised to a degree, but may also involve cruelty and become a form of bullying if performed without appropriate finesse.
A magic store (also magic shop or magician's supply shop) is an establishment which sells materials for performing magic tricks.

The Crazy Gang is a nickname used by the English media to describe Wimbledon F.C. during the 1980s and 90s.
 The name, originally that of a well known group of British comedy entertainers popular in the late 1930s, was used because of the often cheeky and boisterously macho behaviour of Wimbledon's players, who were in the habit of playing frequent and outrageous practical jokes on each other and on the club's manager Dave Bassett (later Bobby Gould and still later Joe Kinnear).
 Their general approach to the game was often derided by others in the sport as unprofessional and their playing style was frequently accused of being basic and unsophisticated in comparison to the style of football played by most leading clubs at the time, despite the fact that it helped them win an FA Cup and also achieve regular finishes in the top 10 of the old First Division, during the six seasons leading up to the creation of the FA Premier League.
