A tourist on a farm asked the farmer why one pig had a wooden leg.
The farmer said, “That pig is the bravest pig I ever saw. “
“So why does he have a wooden leg?” the tourist asked.
“One night, our house caught on fire, and he came inside and woke us all up. “
The tourist asked again, “So, why does that pig have a wooden leg?”
“You can’t eat a pig that brave all at once!”
