One day a blonde walked in to a barber shop wearing head phones. She asked the barber if she could have a hair cut. He said "Sure, but you need to take off your head phones first."
"I can't do that" said the blonde.
"Well you will have to." said the barber.
"No!" argued the blonde.
The barber, becoming very mad ripped off her head phones and the blonde immediately dropped to the floor and died. The barber was horrified, but was also curious about what had just happened. He picked up the headphones and put them to his ears to see what she had been listening to.
All he heard, repeated steadily over and over again was "Breathe in, breathe out. Breathe in, breathe out."
