[Prompt from http://daily-writing.blogspot.com/ . Happy Pi Day!!]
Why were there always swinging saws in this thing? I stood there, analyzing the rate at which each of the five saws swung, contemplating why every single mission into evil villain lairs always involved those stupid things. After another few seconds, I realized that this specific set of swings was working in an alternating pattern of ten seconds and that I could get by easily with one well-timed sprint, I set my sights on the path beyond the saws.
Of course, the next obstacle was a rope connecting two ledges over a pool of water, most likely containing sharks or crocodiles, though I wouldn’t put it past the Fist of Evil to fill the pool with piranhas either.
