breathe in breathe out

There was a blonde who came in a Super Cuts with headphones on and the
hair stylist told her to take them off so he can cutt her hair. And
the blonde said: "No. I'll die." He asked again and she 'no, I will
die." So the hair stylist pulled them off, put them on his counter and
turned around and she was dead. He listened to the tape in her
headphones and it said to 'breathe in breathe out'.
