When I was little, we didn't have a ton of extra money, so we often took week-long camping trips for vacation. On one such trip when I was 7 or 8, I remember walking up to the campground shower facility with a few of my cousins and my older brother. On the wall by the paper towel dispenser was written "For a blow job, call such and such number..." I loudly, repeatedly asked what a blow job was, and my older cousin, trying to shut me up, explained that it was when you accidentally licked the blow dryer while drying your hair. Sitting by the camp fire that night, I matter-of-factly asked the family if anyone had ever gotten a blow job. To this day, I've never more gasps at one time than I heard right then.
