The whole is really deep. It’s huge and dark and seems bottomless, so the man decides to see how deep.
He throws in a pebble and listens, but it doesn’t make a sound.
He throws in a big stick; still no sound
He throws in a huge tree stump he prised up out of the ground; nothing
Suddenly, a dog comes running by and jumps straight into the hole at alarming speed.
The man stares into the hole, dumbfounded, when another man walks by and asks “have you seen my dog?”
“Yeah” he replies, “he just jumped in this hole”
“That’s funny” the other man replies, “I had him tied to a tree stump”
