There were 10 blondes and one brunette hanging on a rope off of mount everest.
The rope could'nt hold all of them so one person would have to fall on to the cliff below and sacrifice her life so the rest could live.
The brunette gives a touching story of how she will sacrifice her life for the rest of them to live, and she will let go and die and after she does this touching speech all the blondes applauded her.
