Draw your own collisions

I think it's under the lorry.

What I expect happened is that the lorry slipped on some poo and as it crashed off the road, its back doors swung open and the sofa fell out. The driver got out and went round the other side but before he could retrieve the errant sofa, he stepped on the fork end of a rake and knocked himself out. At this point our hero turns the corner and is ambushed by the still-lurking soft-furnishing.

+1 - partially for calling me a hero.
