When I was little, my parents decided that I was too young to know the actual words, so instead told me that "the private parts" names were tinkerbell (girl) and tinkerbob (boy). Then, when people would talk about Peter Pan at school (having never seen the movie) I thought that Peter Pan was a movie about peeing. I worried about what "Captain Hook" was until I found out what Peter Pan was really about.
