A few seconds after throwing the anvil in, a goat comes sprinting through the brush and dives into the hole headfirst.
Both men are completely astonished and scared half to death.
A few minutes later, an old farmer comes tromping through the woods and asks the two men:
“Hey have you two seen my prize-winning goat?”
The first guy tells the farmer:
“Yeah! Just a minute ago your goat came sprinting through the woods and dove into the hole! It scared us half to death!”
The old farmer replies:
“That’s impossible! He was tied to an anvil!”
