Well, when I was a kid I guess I'd heard everyone talking about the 'gun' they use to put the studs into your ears when they pierce them for the first time. So up until the time I actually got my ears pierced in about grade 3 I had this weird, scary picture in my head of an old western style house with a porch out front, and you stand at one end and the piercer stands at the other and they carefully aim a nailgun-like thing and shoot your ear from a distance. Freaked me right out.
