Hows this man doing this?

Today has been the perfect Sunday woke up first of all about 10 got a cuppa went back to bed then fell asleep again till 1230! Got up had a crisp sandwich watched x factor from last night then decided to have a shower!

Chilled a bit more. Then decided to get my car washed and visit my Nan! I love having days where I don't have a plan!

Now the photo was from yesterday in Covent Garden, I need to know how this man is sitting like this answers on a postcard please?
