Taub and Kumar search Morgan's office at the retirement home she works at. Kumar wants to know what Taub's problem was this morning, but Taub denies that there's anything wrong. "Come on, man. We're friends," Kumar says. Yeah, you thought you were friends with that Mormon guy last season, and look what he did to you. No one on this show gets to have real friends, Kumar. Sorry. Taub says Kumar is better friends with the nerds he plays Halo against, and suggests that his avatar asks their avatars how they're doing. "I consider you a good friend even if we don't hang that much outside work," Kumar says, still totally oblivious. Poor Kumar. He's going to get smacked down so hard. But wait -- Taub apparently doesn't have the heart to spit in Kumar's earnest face, so he just says he wasn't arguing with House. Kumar says he was. Taub says he was, then. This is a stupid conversation, so I'm glad that it ends with Taub finding a bottle of pills and saying he was right after all.
Taub triumphantly hands House the pills, which are methylthionium chloride, known to cause green urine. Taub figures that Morgan used her mad nursing skillz to fake a seizure with green pee to get attention because she has Munchausen's. Oooo, sorry Taub -- we've already done Munchausen's. House points out that methylthionium chloride is an anti-Alzheimer's drug, so it's not exactly unexpected to find it in a nursing home. Also, House thinks Morgan's incontinence was genuine because it's not easy to pee on one's self in public. Tell that to the guy I sat next to on the bus the other day. I won't be telling him myself, since I'm never, ever, ever taking the bus again. Ever. House says he is a fake seizure expert, and Morgan's was the real deal. And he has a new diagnosis: Morgan is suffering from an overdose of phenol, an ingredient found in throat sprays that she used all winter during her many colds. Taub protests that Morgan would have to chug five bottles of the stuff a day for that to happen. Instead of admitting that that's pretty ridiculous, House says it should be easy enough for Taub to find the evidence of Morgan's throat spray addiction, and sends him off to look. Kumar, on the other hand, is assigned to start Morgan on charcoal to filter out the phenol poisoning. Kumar shrugs and goes off to do that, and House calls him back with "seriously?" Kumar realizes that House was lying about the phenol poisoning because he does think Taub's fake seizure theory has merit, but doesn't want Taub to know.
