Not my parents per se, but similar to Christine's situation.
I was in the intern lounge late one night with a bunch of interns and two monks. The lounge has a kitchen with a "bar" in it stocked with gatorade. One of the monks was standing near the bar and one of the interns was behind the bar. I got up, put my glass on the kitchen, and said to the intern "Hit me!" I meant that I wanted more Gatorade, of course. The monk walks over to me and punches me in the shoulder. It wasn't hard, but it was hilarious.
