Anchor
The grizzled old sea captain was quizzing a young, tyro naval student. "What steps would you take if a sudden storm came up on the starboard?"
"I'd throw out an anchor, sir."
"What would you do if another storm sprang up aft?"
"I'd throw out another anchor, sir."
"But what if a third storm sprang up forward?"
"I'd throw out another anchor, captain."
"Just a minute, son. Where in the world are you getting all these anchors?"
"From the same place you're getting all your storms, sir."
