I'm reminded of the old David Beckham goes to the hairdressers joke......
Becks go for a hair cut and he sits down in the barbers chair and the barber say "ok take ya head phones off".
Becks refuses saying "I can't mate, I must keep them on it's very important I don't take them off".
Barber says "don't be silly how am I going to cut your hair when your wearing head phones".
Beck's "look just do your best, it's a matter of life or death, I can't take them off"
"OK" says the barber and starts to cut his hair, after a while he accidentally knocks the head phones of Beck's head and he suddenly loses consciousness. He quickly picks them up and as he hastily puts them back he hears this voice coming out of them saying "Breath in, Breath out, Breath in"
