‎3 Guys are in a cafe. The 1st guy says "I have the smallest arm in the world". The 2nd guy says I have the smallest head in the world". The 3rd guy says I have the smallest dick in the world! They all go to the Guinness Book of World records. The 1st guy comes back and says I really have the smallest arm in the world! The 2nd guy returns and says I have the smallest head in the world! The 3rd guy comes back and angrily says WHO THE FUCK IS JUSTIN BIEBER?!
