10 blondes and a brunet

there are 10 blondes and a brunet holding onto a bit of rope each . one end of the rope is on one cliff and the other end on another.
the rope is too heavy so the brunet says:one of us will need to sacrifice our life to save everyone else.
All the blondes said no and that they wouldn't do it.
so then the brunet says : ok , fine i will sacrifice myself for all you blodes.
at what the brunet said all the blondes started clapping.
