National Penis Day 

In New Zealand, September 4th is national penis day. Heaps of guys in each of the main cities go to a public place (like The Square in Christchurch), get naked and stand in a formation so as to form a giant penis. Lots of chicks and dirty old men go.

James: "Hey Luke, lets go to The Square to see your mum"
Luke: "What do you mea... HEY!!"
