A man goes to his doctor and complains that his wife hasn't wanted to have sex with him for the past six months.
The doctor tells the man to bring his wife in so he can talk to her and hopefully determine what the problem is.
The following day, the wife goes to the doctor's office. The doctor asks her what's wrong, why doesn't she want to have sex with her husband?
"Oh, that's easily explained. For the past six months," the wife says, "I've been taking a cab to work every morning. I don't have any money. The cab driver asks me, 'Are you going to pay today, or what?' So, I take an 'or what'."
"Then, when I get to work," she continues, "I'm late, so the boss asks me, 'Are we going to write this down in the book, or what?' So, I take an 'or what'.
I take a cab to go home after work and, as usual, I have no money. The cab driver asks me again, 'So, are you going to pay this time, or what?' Again, I take an 'or what'.
So you see, doc, by the time I get home I'm all tired out and don't want it anymore."
"Yes, I see," replies the doctor. "So, are we going to tell your husband, or what?"
