Munchkin brought you the essence of roleplaying. Kill them all and take their stuff! Now the Kneepads of Allure, the Ancient Enraged Plutonium Dragon, the Chainsaw of Bloody Dismemberment, and the Half-Elf Half-Dwarf Super Munchkin Cleric-Thief with the Chicken On His Head have flown off the cards and right into your d20 game! This 48-page hardback will jazz up your d20 sessions as your characters rocket up in power, featuring munchkin classes, races, spells, tips and techniques designed to terrify even a hardened GM!

Hmm I think I should order a copy.
