Georges Day

My dear friend Roy has two birthdays. He was actually born on Saturday 23rd April
However when his mum went to register him on 25th April she registered him as being born that day. So his real birthday is 23rd, and is the one he celebrates, and his passport and birth certificate show his 'official birthday' of 25th!
This however does not fully explain the picture or the title. His surname is Georges making his birthday more fitting.
So why is he wearing a Native American Headdress? That would be our fault. We created a tradition about 8 years ago where the birthday person must wear a birthday hat chosen by the rest of the group. Over the years we have been princesses, vikings, sailors, chickens, bananas, and many many more. I wonder when we'll get too old for all this?
