Another way is to pack mud on your body until it dries. Then have someone peel it away and shower off the rest. It is better to get as much off because this stuff should not go down the drain without a chemical additive chasing it close behind in order to keep the clay from closing off you pipes.
The other option is to not wash off the clay, have someone glaze you (with a low firing, non toxic glaze, and have people set the glaze with hairdryers. You could then find a rent free home in a living museum.
