Sadly, I've never played PnP.
I was close to playing DnD once and had just started to create a character with some friends who played it quite a bit when my mom walked in and asked what we were up to. Upon hearing Dungeons and Dragons she immediately thought of Mazes and Monsters or something and thinks I'll start worshiping the devil or sacrificing virgins or who knows what. I tried to explain to her that wasn't what I'd do with virgins given the chance and not to worry because I already worshiped the devil. She wasn't amused. When she finally came around the DnD friends had moved far, far away and none of my other (lamer) friends were into it and so it never happened.
