Flight fifty has a pretty rough time above the ocean. Suddenly a voice comes over the intercom: "Ladies and gentlemen, please fasten your seat belts and assume crash positions. We have lost our engines and we are trying to put this baby as gentle as possible down on the water".

"Oh stewardess! Are there any sharks in the ocean below?" asks a little old lady, terrified.

"Yes, I'm afraid there are some. But not to worry, we have a special gel in the bottle next to your chair designed especially for emergencies like this. Just rub the gel onto your arms and legs".

"And if I do this, the sharks won't eat me any more?" asks the little lady.

"Oh, they will eat you all right, only they won't enjoy it so much".
