There was a tourist on a farm and he 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.

''Well one night our house caught on fire. And he came into our house and he woke us all up.''

''So,'' the tourist asked again, ''why does that pig have a wooden leg?''

''Well, a pig that brave you can't eat all at once!
