My mom's mom would always stay over in christmas mornings when I was a kid. My Dad, Brother and I were really into Prince of Persia so obviously we got the sequel for christmas. We fired up the xbox, watched the intro cinematics, and suddenly it cut to the ass of the villain walking up the steps of her boat. Not just any ass, but her ass in an S&M style body suit with a thong. Grandma laughed her loud and jovial laugh, and my dad (who was playing) froze with embarassment.
Fun stuff!
