Spotted...

You see, I read that as "Japan jet engine sucks off object"...

Spotted the one himself, riding down Oxford Street this morning, looking all confused when I yelled from the top of Wardour Street.

I'm bringing my own tarmac next time.
Aah, that was you.
I heard someone shout but in my hungover daze couldn't work out the direction of the voice.

Mystery solved.
