A mild mannered man is tired of his wife always bossing him around, so he decides to go to a psychiatrist. The doctor tells him he has to develop self esteem.
The doctor gives him a booklet on assertive training. He reads it on the way home.
When he walks through the door and 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 my dinner on the table. Now get upstairs and lay me some clothes on the bed because I'm going out with the boys tonight. Then draw my bath. When I get out of the tub guess who is going to dress me and comb my hair?"
"The undertaker." she replies.
