The Well

Return back from fishing, Mike and Jim walked along the path back to the village, when suddenly Mike noticed a gaping hole of a well just beside the path, and almost plunged to it.

Mike,"Wow, I almost fell into the well. Hey, Jim, lets see how deep the well is."
Jim,"How?"
Mike,"Maybe we can try to throw a rock and see how long until it will make a noise of it hitting the ground or water."
Jim then found a small rock and throw it to the well.
Mike,"Wow, the well must be so deep. I did not hear any noise of it."
Jim,"Maybe it's just not big enough. Try to throw that coconut instead."

Mike,"Whoa, I did not hear it hit the water or the ground. It must be pretty darn deep!"
Jim,"Well, maybe we need to find even a bigger thing to throw inside it."
They tried to find something.
Jim,"Hey Mike, look what I found here. Help me out with this, will you!"
Apparently they found a block of railroad bed concrete. Together, they carried the block to be thrown inside the well.
Mike,"Holy cow! Even that does not make any noise!"

Suddenly, a goat came charging in to them swiftly. Fortunately Mike and Jim was able to evade. But unfortunately the goat was not and went straight into the well.
Jim,"Crazy goat! It almost hit me!"

A few moments later, old farmer Joe came carrying a shotgun and yelled to them,"Hey, did you see the person who stole my goat? I was just left for a pee and it was gone."
Mike,"No we did not see anyone carrying a goat. But we saw a goat charging us and went straight into this well! Maybe it was yours?"
Old farmer Joe said,"No way my goat can run by itself, I tied it up to a block of railroad bed concrete!"

Jim and Mike,"???"
