When I was a kid, the entire family, all eleventy-thousand of us, would meet at my grandparent's house for the holidays. One of my cousins was about the same age as me, and one year we spent the entire post-dinner day pinching our younger (girl) cousins' backsides, shrieking, "It's time for your Christmas goose!" (everything's funny to a twelve-year-old hillbilly boy). We thought it was a hoot until my psycho Uncle Bobby suddenly jumped us and decked us both.
True story, a real Hallmark Moment.
