that's funny. I told my wife, thinking that this was strange, and she said "they want it for the pictures." Apparently, folks frame the pictures from the calendar or use them (as you said) for scrapbooks.
I had a day where I sold 3 rat traps and $200 worth of male enhancement pills. There's nothing saying the same guy bought both, but it struck me as a really funny combination. I also can't imagine which of my hubs they were reading that reminded them they needed enhancing.
