mountain climbing

Two mountain climbers
reached the top of a
mountain when one fell
into a large crack.
"Are you ok?", the other
one asked.
"Not really", said the
other.
"Ok I'll drop a rope down
so I can pull you up".
"I can't, my hands are
broken" said the other
again.
"Ok then try tying it to
your legs."
"I can't my legs are
broken."
"Ok then put it in your
mouth and I'll pull you
up."
"Ok!"
The man puts it in his
mouth and is pulled by
the other. Half way up,
the one pulling asks "are
you ok?"
The other one answers
"yeaaaa..."
