3 guys are in a cafe

one says: ive got the smallest arm of the world!

another says: ive got the smallest head of the world!

last one says: ive got the smallest dick of the world!

the 3 guys go to Guinness; World Records.

first one goes first and returns happy: ive really got the smallest arm in the world!

second returns happy too: ive really got the smallest head of the world!

last one returns angry and screams; WHO THE FUCK IS JUSTIN BIEBER?
