When I was about 8 I asked my dad if we could play "the naked man game." My dad, trying not to panic, asked me what it was. I responded "it's the one we play when [the babysitter] is over." He then asked me to show him where the naked man game was, so I took him to the closet, opened the door, and pointed up to Operation.
He told me years later that he nearly had a heart attack.
