There are some things you could only ever see in London.
Thankfully, due to the rise of social media and camera phones, we can now record many of these bizarre and weirdly wonderful events and share them with the world.
Using the hastag #OnlyinLondon, that's exactly what some Twitter and Instagram users have been doing.
From a photo of a dedicated horse owner taking his pony for a walk through the West End, to a blinged-out sparkly car, to accidental celeb spotting of the highest order - it's all going on, but only in London...
We'd love to hear your #OnlyinLondon stories. You can tweet us @getwestlondon or email.
