This guy from the city took a vacation to a ranch.
While there, he walked into the barn.
The blacksmith had just taken a horseshoe out of the fire and set on his anvil.
The city guy didn't know it was hot, so accidentally picked it up. Burning his fingers, he quickly threw it down.
The blacksmith saw this and asked, "Pretty hot, huh?
The city guy said, "Nope! It just doesn't take me long to look at a horseshoe.":p
