THIS IS WHY WE CAN'T HAVE NICE THINGS!!
Now I have to think about this savage next time I get on an airplane and go to use the tv in front of me! I have to actually think: "Hmmm, did some moron rub their disgusting feet all over the screen I have to touch"?
It's just wrong, man, WRONG I SAY!!!!
You better bust out the damn clorox wipes after that flight!
