Two guys were hiking in the woods and decided to have lunch at one of the picnic grounds along trail. They discovered a big hole at the edge of the picnic area and wondered how deep it was. So they decided to drop in a pebble and listen for it to hit bottom. They dropped in a pebble and nothing happened. No noise. They dropped in a boulder and there was still no noise. They decided to scout around for something really big to drop in the hole and came across a railroad tie. They pushed and pulled it over to the hole and dropped it in. Still no noise.
Suddenly a goat ran out of the woods and jumped into the hole.
As they were packing up their lunch, a farmer came by and asked if they had seen his goat. They said the only goat they had seen that day had been running in the woods and had come out and jumped into the hole.
The farmer said, ‘It couldn’t have been my goat. He was tied to a railroad tie!’
