This movie is over 40 years old and still considered a classic comedy for good reason. One reason is the cast. The main characters are played by such classic comics as Sid Ceasar, Jonathan Winters, Milton Berle, Ethel Merman, Buddy Hacket, and Mickey Rooney. Even the minor characters become cameos with such people as Jerry Lewis, Jim Backus, Carl Reiner, Don Knotts, and the Three Stooges showing up, sometimes only for one shot. Everyone, no matter if they are have a starring role or a cameo make the most of their screen time for laughs.
