Best way to hoist an over-sized pilot out of the cockpit? (post landing)

So today I encountered a novel situation at the airfield. The diminutive line boy and I were called upon to hoist an over-sized pilot with a "bad knee" out of his glider (after landing.) Enthusiastic to help with all aspects of "ground handling", I jumped right in, and I ended up straining my back.. Bummer.

So how does one handle this situation better?

I thought we might keep a pole on hand with a nice loop of nylon webbing that we could slip under the armpits of the pilot, pass the pole above him and lift on both sides of the glider with 2-4 hefty men. Sorta like a palanquin. Or we could remove the wings, roll the fuselage on it's side, and "spill" the pilot onto the ground.

Is there something wrong with this picture?
