Don't forget that there were actually SIX stooges over the years; Moe and Larry were always there, and the third stooge was (in order of appearance) Shemp, Curly, Shemp (again), Joe Besser, and finally Joe DiRita, who played the third stooge in the last movies that were done.
So, since there were SIX stooges, total, who are the other three?
