When I hear the word scrum I am always reminded that my school stopped playing Rugby because a kid in the next town got his back broken, in a scrum. So from then on we played football (soccer) in Rugby kit, until eventually all the kids had grown out of it, or left. Similarly, if you sprint and sprint and sprint you will collapse from exhaustion.

I often wonder if they picked these words because they knew nothing at all about sports, of if there is a coded warning in them...
