That's a deep hole!

Two guys were walking through the woods one day. When they found a small clearing in the woods, they noticed that there was a big hole in the middle of it. Being curious, one guy said to the other "I wonder how deep it is?" So he picks up a small rock and drops it down the hole. They both listen for the rock to hit bottom, but they don't hear anything. So the other guy picks up a larger rock and drops it into the hole. Again they listen, but hear nothing. "That's a pretty deep hole!" said the second guy. After a few more rocks were thrown in with no sound, the first guy says to the other guy, "Hey, help me throw this old tree trunk in there. That'll make some noise for sure!" So the men throw the huge log into the hole. As they're waiting for a sound a goat suddenly busts through the treeline running as fast as it can towards the hole! When the goat reaches the hole, it jumps up in the air and goes straight down into the hole.

As the two men were standing there in shock as to what just happened, a farmer walked into the clearing. The farmer asked the guys "What are you two doing out here?" The men explained the whole thing that just happened with the goat. The farmer scratches his head and said "Hmmm, yep that is pretty unusual. Well no worries, I know that it wasn't my goat. You see, I keep my goat tied up to a huge log."
