And then we go to the Foxhole, that hot new lesbian bar! Hadley appears to have a line-up of martinis on her table, all purchased for her by interested women. Even though she's in there with a man. House is trying to find a straight woman in the crowd, using Hadley's gaydar. He picks out the bartender, figuring that she might be straight but just work at a lesbian bar. Meanwhile, the bartender has short blonde hair and is the most stereotypically lesbian-looking woman in the entire room except for House. House casts doubt on Hadley's gaydar, saying it failed when it came to Ted. Hadley says Ted came into PPTH with his bride, so, extenuating circumstances. Then she gives her opinion on the matter, saying "it's unbelievable what he's doing to her," and that no matter how much he thinks he loves Nicole, he'll always "need" to have sex with men. House says Taub loves Mrs. Taub but "needs" to have sex with other women. Hadley says Taub sucks, too, but Ted has to "deny his identity" to be faithful to his wife. So does Taub, though, if his "identity" is "cheating scumbag." "It's easier to say no to dessert than to pretend you don't eat," Hadley says. And then House and Hadley psychoanalyze each other and their problems. By the way, how did this lesbian bar become popular? It's all gray and cold and boring. Even the drinks it serves are boring. Is this what all lesbian bars are like? House gets a call from Taub, who says the spinal fluid came back negative for infections, which means it's not POTS somehow. Hadley downs her martini, her hand SHAKING NOTICEABLY. DUN DUN DUNNNN HUNTINGTON'S. House notes that Ted's headaches got worse after they did the spinal tap. He thinks Taub "sprung a leak" in Ted's spine and his spinal fluid is leaking out, causing the headaches. Except ... didn't those headaches start before the spinal tap? That's what Chase asks, and House says something about "low pressure" in Ted's brain that caused the POTS, which is apparently back on the table. House orders them to patch the leak and give Ted some artificial spinal fluid. Another martini arrives in front of Hadley, courtesy of another interested lady. Meanwhile, Hadley has, like four martinis in front of her already, so what is this woman trying to do? If she drinks that sixth martini, she'll be too wasted to do anything with you, and she has five other martini-buyers in line before you. And she's there with A MAN, which would tell me that she probably isn't interested in women, at least not tonight.
