There is a scene in the movie where Jerry Lewis answers the door for a Gangster-looking man who has come to pick up one of the ladies of the house for a date. While waiting for her,he falls victim to Jerry Lewis' character's clumsiness. During the number of damages Jerry does to the man's clothes,he tries to fix it while the man just stands there instructing him to "fix it". Watch Jerry Lewis closely, he will be literally cracking up at the man's actions and you can even hear him laughing at one point. He is laughing so hard he turns his head from the man. I guess since Jerry's back is turned the whole time, maybe it was thought that people wouldn't catch it. I didn't until I watched it lately although I've seen this movie from childhood to adulthood.It's funny seeing the funniest man in the world being cracked up.
