[nilesfunnies] Fw: Talking of blondes ...

On the first day of training for a charity parachute jump, the
instructor made an important point. "Start preparing for landing when
you're at 300 feet."

One student, a blonde as it happens, asked, "How do you know when you're
at 300 feet"?

"A good question. At 300 feet, you can recognise the faces of people
on the ground."

She thought about this for a moment and said, "What happens if
there's no one there I know"?
