Three swimmers are on the starting blocks at the Paralympic games. The first one has no arms, the second one has no legs, and the third one is just a head standing on the block. The race starts, the first two swimmers jump in and start swimming, someone pushes the head in. They go at it like crazy and finally, the guy with no legs reaches the finish line. Everyone cheers, he is so happy, but he looks around and sees bubbles coming from the water. He dives and grabs the head that was underwater. The head coughs some water and says: "I train for five years to swim with my ears and just before the start some idiot comes and puts a swim cap on me!"
