Spray–On Mud — 'It's dirt cheap!'

"Spray–On Mud is a specially formulated spray-on product for anyone that wants to give friends, neighbours, colleagues or just anyone at all, the impression that they have been off-road or, at the very least, out in the country for the weekend."

Lots of potential uses for this nifty product, way beyond that recommended by the website's copy (above).
