One day a group of wales were swimming around in the ocean when a warning came to the group to scatter.  One of the whales had just been harpooned by a whaling ship.  The other whales all broke formation to confuse the harpooners as to which direction to aim in and dived deep to the depths of the ocean, well out of range of the whaling ship.

About an hour later, when the group had regathered and counted their losses, the head whale said "Look, I'm getting rapidly sick of this situation, what with all those bloody whaling ships constantly coming out here and decimating our numbers.  I think it's time we took action to put a stop to it once and for all."

"And what do you propose that we do?" asked one of the other whales.

"What I would suggest" said the head whale "would be that as soon as the next whaling ship is sighted the whale who spots the ship raises the alarm, at which point we all converge, dive beneath the ship and then let out a sharp burst from our blowholes and capsize the ship.  If the ship sinks then that should make the whalers think about coming back and trying it again."

A big cheer comes from the group of whales, all enthusiatic to try out the plan.  Suddenly another whale raises a fin to get the head whale's attention.

"Yes, Diana?" says the head whale.  "You have a question?"

"No, I have a suggestion" replies Diana.  "Once we've capsized the ship why don't we go around and eat as many of those damned whalers as we can?  That ought to teach them a lesson - particularly if there's a large number of casualties."

And with that one of the other whales cries out "My God, no!  I don't mind doing the odd blow job but I'm not swallowing the seamen!"
