Whales

A male whale and a female whale were swimming off the coast of Japan when they noticed a whaling ship. The male whale recognized it as the same ship that harpooned his father many years earlier. He said to the female:
"Let's both swim under the ship and blow out our air holes at the same time and it should cause the ship to turn over and sink. This they tried and, sure enough, the ship turned over and quickly sank. Soon however, the whales realized the sailors were swimming to the safety of the shore. Enraged, the male whale told the female, "Let's swim after them and gobble them up before they reach the shore. At this point, he realized the female was becoming reluctant to follow him. "Look," she said, "I went along with the blow job, but I absolutely refuse to swallow the seamen".
