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 had harpooned his father several years earlier. He said to the female whale, "Let's both swim under the ship and blow out of our air holes at the same time. That should cause the ship to turn over and sink."
They tried it and sure enough, the ship turned over and quickly sank. However, the whales soon realized that the sailors had jumped overboard and were swimming safely to the shore.
The male was enraged that they were going to get away and 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 absolutely refuse to swallow the seamen."
