Strike a happy medium

While driving down the road the motorist saw a roadside stand which had a fortune teller sitting under an umbrella. She was just sitting there smiling and laughing. The motorist passed on by and went a couple of miles on down the road. All of a sudden he spun his car around and sped back toward the fortune teller. As he got closer to the still laughing fortune teller he began to slow down. He pulled up next to the woman and jumped out of his car and suddenly began slapping and beating her. A policeman passing by screeched to a stop and wrestled the man to the ground. After cuffing the man he stood him up and asked him, "What do you think you're doing?" After a moment the man replied, ... "Well, I've always wanted to strike a happy medium."
