My mate Harry was on a Sunday afternoon stroll through the countryside. As he walked through a meadow, he noticed a hole. Wanting to see how deep it was, he threw a stone down. No sound. So he threw a medium-sized rock down. Nothing. Getting a little frustrated now, he threw a boulder down. Nothing. As he searched about, he spotted a railroad beam. He hauled it, and shoved it in. No sound.
Confused and exhausted, suddenly he saw a cow running at him, full speed. Bang and ran straight through him. Whilst scratching his head with the randomness a farmer then came walking up. “How deep is this hole?” Harry asked. “Oh. That’s the bottomless pit. Say, have you seen my prize cow?” the farmer replied. “Yes sure she’s just run past me” The farmer said, “Oh well. She can’t get far. She was tied to a railroad beam.”
