House plays the piano. There's a stiff drink on top of it. Chase would not approve. He switches to "Happy Birthday." Seemingly having a sudden epiphany, he picks up Friedman's journal. He calls a doctor, who hangs up on him because it's late. He then pretends to be a doctor calling from London, and Hugh Laurie's Brit-playing-an-American-faking-a-British-accent is pretty genius. Stymied, he leaves...

...to hold late-night court with the Martins. He explains that Friedman's mom's only initial symptom before the supposed schizophrenia was a headache, which no doctor could really figure out. House asks what other problems present with psych symptoms. Cameron FINALLY makes herself useful by mentioning a genetic condition wherein the body accumulates too much copper. Chase calls it as "Wilson's disease." I thought Wilson's disease caused people to follow hot Englishmen around at the expense of their jobs, but I'm not a doctor. ["Oh my God, my family doctor thought I had that last year! I didn't, but it took two 24-hour urine collections to rule it out. (I realize you didn't ask, but aren't you glad you know?" -- Wing Chun] House likes the diagnosis. Foreman complains that if any of them did this, he'd fire them. Dude, if none of you have been fired yet, I think you're safer than a tenured professor at a state university. Foreman clarifies that House is hoping instead of questioning. House reveals that Friedman's mom made an appointment with an ophthalmologist before she took up residence in Crazyland, and Cameron notes that Wilson's presents with cataracts. House agrees: "It also causes slight cirrhosis, which Doctor Chase so eagerly attributed to alcohol." He asks what they're still doing there. Seriously -- get this bitch cured so we can go have a drink!

House wakes up Friedman's mom, and tells her he doesn't think she's crazy. Friedman's mom: "Neither do I! But I'm crazy." Heh. The Martins set her up to check her eyes, and Foreman says that if she has Wilson's, she'll have copper-colored rings around her eyes called "Kaiser-Fleischer rings." Long story short? She has them. So copper was the culprit in both of my episodes. If the writers of House are trying to convince me that pennies should be taken out of the U.S. monetary system, I can just tell them that they're preaching to the choir.
