Good grief!
The guy's FEET can take out a whole room??
This guy needs a course in FOOT CARE! He's prolly got encrusted dead skin, toe jam, athlete's foot and I don't know what else...
He'll need a pumice stone for scraping in the shower, and lessons in how to use it. Meanwhile, foot powder is a good temporary measure, although it shouldn't be neccessary once his feet are healthy again.
Does this guy brush his teeth regularly? Just askin'...
