LOL! DH does this as well, no matter what the sandwich. He also butters crackers for cheese and cucumber. I have to admit, butter on toast before the peanut butter goes on is pretty darn good, so I can get behind that one, at least, it does make it less claggy and dry. And butter on crackers with cheese is ok, too. But butter on any other sandwich (unless it's a toasted sandwich) is gross to me. Is butter really necessary on a bacon butty?!
