Reminds me of a joke:
Two guys are out walking in the woods when they come across a large hole. Wanting to see how deep it is they find a rock and throw it in, but it doesn't make a sound. They find a bigger rock and throw that in but it too does not make a sound. They look around some more and eventually find a big railroad tie, lug it over to the hole, and throw it in. Still no sound. Shortly after that a goat comes along running 60mph and dives headfirst into the hole, but even that doesn't make a sound. The two guys give up and are about to walk away when a farmer walks into the clearing and asks them a question.
"Have either of you guys seen a goat around here?"
One of the guys responds "Yeah we saw a goat come running through here a minute ago. It dove right into this hole."
"Well that couldn't have been my goat" says the farmer. "My goat was tied up to a railroad tie."
