Re: House 5x05 "Lucky Thirteen" - Discussion and Spoilers
I did note that when House cut the onion that HIS eyes didn't tear up.
He kept turning his head away, widening his eyes, then dobbed them with a handkerchief afterwards, so I'm pretty sure his eyes did tear up. Of course, that was before he ordered the "artificial tears to maximize the visual impact of this moment."
Build a man a fire, and he'll be warm for a day. Set a man on fire, and he'll be warm for the rest of his life.
