Bill walks into a bar and finds his friend Joe sitting on a stool. "Joe," Bill says, "I'm glad to see your wife finally let you out of the house." "Things have been different with my wife," Joe says. "In fact, just the other day, I decided to show her who was boss." "How did you do that?" asks Bill. "I simply said to her, 'Mabel, we are going to have it out right now, and I am going to show you who is the boss 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."
