Three guys are talking in café.
The first one says - I have the smallest arm in the world.
Second one says - Well, I have the smallest head.
Last one says - You don't believe me but I have the smallest dick!
Three guys decide go to Guinnes World Record. After weeks they met again.
The first one says happily - I've really got the smallest arm in the world and got the title in Guinnes!
Second guy says pridely - I've got the title too for having the smallest head.
Last one is a bit late but finally shows up angry and screaming - WHO FUCK IS JUSTIN BIEBER?
