Pillow Fight Day 2015: Hundreds of people gather in a feather-filled Trafalgar Square
There really is a day to celebrate everything.
Hundreds of Londoners have gathered in the center of the capital to celebrate national Pillow Fight Day – and it ended up rather feathery.
Scenes at Trafalgar Square saw young and old bracing themselves for a feather-filled fisticuffs along with hundreds of other cities around the world for International Pillow Fight Day.
Anyone disappointed to miss out – and let's be honest, who knew it existed – can put a date in the diary for the annual day which falls on the first Saturday of April every year.
Here's what it looked like.
