PEDRO, MARIA & Gonzalez

 When Pedro and Maria got married, he was a very experienced
 man, but  she was totally naïve. On their wedding night, when Pedro
 removed his clothes, Maria asked, 'Pedro! What is that?'

 Pedro was a quick thinker. 'Maria, I am the only man
 in the world with one of these.' And then he proudly showed her what it
 was for. Maria was pleased.

 After the honeymoon was over, Pedro returned to work, only
 to return home to find an upset Maria waiting on their front porch.
 'Pedro, you said you were the only man in the world with one of those
 and yet today, when I saw Gonzalez changing his clothes behind the
 shed, he had one, too!'

 Ever fast on his feet, Pedro said, 'Oh, Maria, Gonzalez is my best friend.
 Since I had two, I gave him one. So he is the only other man in the
 world with one.' A sceptical Maria accepted this answer, but when
 Pedro returned home the next day, an agitated Maria was waiting on the
 porch. 'Maria? Now what's wrong?'

 'Dammit, Pedro. Why have you given the better one to Gonzalez!'
