Three men are sitting in a bar discussing their physical attributes.
The first guy says "I have the biggest hands in the world, I am off to tell the Guinness Book Of Records", so off he goes.
The second man says "I have the smallest head in the world, I am also off to tell the Guinness Book of Records", so off he goes.
When they both return they see that third man is really upset. They ask him what is wrong.
"Well, I thought I had the smallest penis in the world, so I contacted the Guinness Book Of Records also.......who the hell is is Justin Bieber?"
