There was a man who couldn't stand his wife's constant nagging, so he decided to try and train her like he would a dog. Every time she nagged him, he would give her a treat.
After a few weeks of this, the man's friend came over to visit and marveled at how well trained the wife was.
The man proudly showed off his skills, saying, "Watch this!"
He turned to his wife and said, "Honey, what's 2 plus 2?"
The wife sat there thinking for a minute before finally blurting out, "Um…4?"
The husband immediately reached into his pocket and pulled out a treat, handing it to his wife.
The friend was amazed and said, "That's incredible! I wish my wife was as well trained as yours."
The man replied, "Oh, it's not all sunshine and rainbows. Just the other day, she peed on the carpet."
