It's my theory that when Sanzo's not being verbally abusive to his travelling companions, committing crimes against Buddhism, or ordering people around while he sits on his ass and does basically nothing*, he certainly MUST be rigorously maintaining his underarms. I mean, to have that level of silky smoothness must take a lot of work. Perhaps he uses that new Dove underarm conditioner... He actually probably waxes his underarms (or uses Nads of Australia), but this is a funnier picture to draw. Fun fact: the medical term for 'armpit' is 'axilla.' Oh, Sanzo, I would wax your axilla anytime...HUBBA HUBBA (and why doesn't anybody use the expression "hubba hubba" anymore?).
*I can say this because he's my favorite character...nothing but love do I have for THA SANZ.
