The Three Stooges boast a legacy as one of the most influential comedy acts ever, but the changes to their lineup breed some confusion. Its hard to overstate the importance of the Three Stooges to American comedy. Over the years, the trio put out hundreds of comedy shorts in which they occupy a variety of jobs, before causing the situation to descend into chaos with their trademark slapstick violence. The groups legacy is decades worth of some of the best comedy movies, short films, TV appearances, and even a controversial remake from the Farrelly brothers.
