True Story: One year my parents attached math problems to all our presents on Christmas. In order for us to receive our gifts we had to solve the problems. They weren't easy to solve, either.
My mom and dad were howling with laughter as we struggled to get through the work. We were pissed.
At the time we absolutely hated it, of course. But now that I'm older I'm like, "Yes, yes. Of course." Spoiled little American brats getting pissed that we had to do something educationally enriching in order to receive the litany of gifts our parents had worked so hard in order to buy for us.
