morkinva is right - Curly, Shemp and Moe were brothers in real life. Curly's real name was Jerome, Shemp's was Samuel, Moe's was Moses.
Blain, when you say "features", if you mean the full-length movies like The Three Stooges meet Hercules, they are crap. Stick to the 18-20 minute shorts (the ones they show on TV). Get the ones with Curly or Shemp as the third man, and avoid the ones with Joe (Joe Besser) and Curly Joe (Joe DeRita). When they started making the feature-length movies they were getting pretty old and they aren't as funny IMHO.
