Ok, that was gross

 I walk into the shower area at the pool today and I see a guy pick up his dirty, inside out sock and wipe his face and clean out his ears with it.  In hindsight, I'm surprised I didn't say anything while it was happening.  I think I was just in shock that it was actually happening... call it literally "speechless".
 
Not like I'm some sort of clean freak, but jeez... The sock you wore working out and sweating in... on your face?!
