A mild mannered man is tired of his wife always bossing him around, so he decides to go to a Psychiatrist.
The doctor gives him a booklet on assertive training. He reads it on the way home.
When he walks through the door, his wife comes to greet him. He tells her,

"From now on, I'm the man of this home and my word is
law. When I come home from work I want dinner on the
table. Now, get upstairs and lay out some clothes on
the bed because I'm going out with the guys tonight.
Then draw my bath. When I get out of the tub, guess
who's going to dress me and comb my hair?"

She replied coolly, "The undertaker?"
