#1 A man driving by a farm noticed a pig with only 3 legs. He of course stopped to inquire of the farmer. Seems there was a fire, and this pig dashed into the burning barn to save the farmer's daughter.
The passerby asked if dashing into the fire is the reason the pig only had three legs. The farmer said "No, that's not the reason". He explained further: "It's just that I think so highly of this pig because of his bravery in the fire, it's a shame to eat him all at once".
#2 A New Zealand farmer walks into the house with a sheep draped over his shoulders and finds his wife inside.
Quoth the farmer: "This is the pig I screw when you have a headache".
To which the wife retorts: "You dummy, that's a sheep, not a pig".
The farmer responds: "What makes you think I was talking to you?".
Maybe you have heard about the famous Christmas pig named Chet. He gave his life for a Christmas dinner and ever since then we sing a song of his sacrifice - you know, Chet's nuts roasting on an open fire
