[Joke] Headphones - Surd Joke

An surd goes to a barber shop wearing walkman headphones. He tells the hairdresser: "Cut my hair please, but do not remove the headphones." The hairdresser does his job but needs to get under the headphones to finish his work. He removes the headphones thinking that the surd will never even notice. The surd falls to the floor, chokes, turns blue and dies. The hairdresser picks up the headphones to see what he was listening to and hears: "Breath In, Breath Out, Breath In, Breath Out....."
