Begin To Clap

There are 13 blondes and a brunette hanging on a rope off Mount Everest.
The rope is about to snap until a blonde says :
- One of us has to let go for the rest of us to survive ! Or else we'll all die !
So the 13 blondes start arguing and start saying.
- You jump off !
- No you jump off !
So finally the brunette says :
- Fine... I'll let go for the rest of you to live and make it up this mountain.
A second later, as all the blondes are so happy, they begin to clap.
