Timid Patient
A psychiatrist advised his timid little patient to assert himself. "Don't let your wife bully you. Go home and show her who's boss."
The patient went home, slammed the door loudly and roughly seized his wife. "From now on," he snarled, "You're taking orders from me, see? You're gonna make my supper this minute, and when it's on the table you're goin' upstairs and lay out my clothes, see? Tonight I'm goin' out on the town - alone, and do you know who's going to dress me in my tuxedo and black tie?"
"You bet I do," was the answer, "The undertaker!"
