"A Wee Lie" joke

In a village in South Africa, there was a young man who was what some people call a Casanova, good with the ladies. He had all kinds of ladies. He liked them all... fat ones, short ones, skinny ones, it didn't matter to him.
The trouble was that he had a true love, a virgin that he was saving for marriage. This innocent virgin, her name was Mary, knew nothing about sex. Of course, our Tiger of the Village wanted to keep things that way.
Eventually they were married and on the wedding night Mary was very impressed with sex. She told her new husband that she did not know a man was built that way. What a wonderful thing men had to please women.
Our Tiger didn't want her to think that all men were the same, so he told her, "I tell you something, Honey, I am the only man in the world with such a thing." She believed him!
Our Tiger of the Village was a sheep herder and had to go to the hills for weeks at a time. He had been gone for a couple of weeks, when he came back and began to look for his new bride. When he got to their hut, she wasn't there. He then went down through the village looking for her. "Mary, Mary, where are you?"
Finally, he meets up with her on the street. Mary appears to be very angry and frustrated.
"You son-of-a-bitch, you bastard, you good for nothing!!" she screams and begins to hit and fight with him.
"Hey whoa, what's the matter baby, what did I do? I didn't do nothing. Why are you mad at me?" our Tiger asks.
Mary says, "Yeah, you asshole, you know Sancho, the lazy one from across the street? Well, he has one also," and she points to his genitals.
Our hero thinks about it, she must have seen this guy taking a leak. "Hey Honey, I tell you something, you know what? Sancho, he is my best friend. I used to have two of them and since Sancho is my friend, I gave him one." Our Tiger is all smiles and goes over to hug Mary.
Now, she's even angrier and begins to punch him over and over. "You stupid man, you dumb ass," she yells at him, "YOU GAVE HIM THE BEST ONE!!"
