Not so much a stupid question as one that seemed a little odd in its context.

I used to work in a book store. One of the books we regularly kept in stock was a handbook on anger management used in a local counselling program. It was a program that abusive partners, among others, attended. One day a cheerful young man called to ask if we had the book in stock and then asked us to hold a copy for us; he would be in to collect it that afternoon. Fine no problem. Then he asked, "Do you have any books on boxing?"
