An exploit of several loopholes. The original is a fighter carrying around a bag of rats, with the purpose of throwing them at an enemy, then using Whirlwind Attack to attack them all in one round, and Great Cleave to get a free hit at the actual enemy for each rat killed. A similar issue occurs in the 4th Edition with the Warlock. Some powers like Misty Step activate upon the death of a cursed enemy. This could be exploited by carrying a bag of rats, cursing them, and killing them at the appropiate times, in order to use Misty Step at will.
