If there's one recording that will strike fear in to the hearts of anyone, it's the FitnessGram 20-Meter Pacer test. Recite the entire script up until the instrumental kicks in.

As someone who ran Cross Country for three years and Track for two years in high school, I must say that I truly enjoy this challenge. It is very, very taxing once you start to reach your limit, but the workout is very rewarding and a great...well...test of endurance! It's also one of my favorite memes of all time, up there with Rick Rolling, the John Cena Theme song, and Y can't Metroid crawl?
