Nice for some humour, Mike, but not so nice if someone actually does it. Enough methanol could soak through the skin to do damage such as turning the lens of the eyes white.
Ethanol and isopropyl alcohols are both pretty cheap. I recently read to use about 1/4 of the various tanning gels mixed with alcohol to get a thin, cosmetic-type mix that is easier to apply. Still kills virtually all germs if you use enough to keep the skin wet for several minutes.
