Harry (Harry Gribbon) and Beulah are married when the story begins. However, Harry has plenty of evidence that Beulah might be cheating on him...but he's VERY slow to notice the signs. However, when Harry tries to catch his wife in the act with another man, police catch him climbing the fire escape and assume he's some kissing bandit. This leads to a visit with the police psychologist.
I've seen quite a few Harry Gribbon comedy shorts and I keep hoping I'll find one I like. But I just didn't enjoy "Who's Crazy?" because it was unfunny and very broadly acted. I wanted to like it...but just didn't.
