A childhood belief about swearing

When I was a kid (actually, until about two years ago), my dad, my brother and I used to go skiing together almost every weekend. Well, on one of these outings, we were at the top of the hill, trying to decide which run to go down, and we noticed that one of the runs was called "FLICKER," written exactly like that, in all capital letters, except the "L" and the "I" were a little too close together, so my brother's eyes lit up as he pointed to it and said "Hey Emily, look what that hill's called!!!" My dad almost killed himself laughing. It was even funnier because, at this particular ski place (which catered to families), there were signs all over the place that said "No foul language," with a big red X through a picture of a tough-looking guy with cartoon expletives coming out of his mouth. So, my brother couldn't understand for the life of him why the people at the ski hill would break their own rule by giving one of the runs such a "vulgar" name, lol.
