"Who's the boss" joke

Bill walks into a bar and finds his friend Joe sitting on a stool.

"Joe," Bill said, "I'm glad to see that your wife finally let you out of the house."

"Things have been different with my wife," Joe said. "In fact, just the other day, I decided to show her who was the boss."

"How did you do that?" asked Bill.

"I simply said to her,' Mabel, we are going to have it out right now, and I am going to show you who the boss is in this relationship'."

"What happened?"

"Well, I don't want to brag, but I managed to get her on her hands and knees."

"How did you do that?"

"I was hiding under the bed at the time."
