Their conversation ends when House suddenly appears in the lab behind them. The results will take another hour, which is too long for House to wait. Instead, he says they're looking for poop with a high fat content. Fat floats. There's a Monty Python reference. And then House drops the droppings into a pitcher of water. If the log floats, Kumar's diagnosis is correct. If it sinks, it's back to the drawing board. That can't be the best scientific way to do this. In fact, I remember reading once that scientists don't really know what makes a poop float or sink, or which one is healthier. Don't ask me what I was reading or why, because I seem to have blacked it out. But I do remember that. Anyway, the poop sinks, so House decides to reconsider Taub's apnea diagnosis.
So while Emmy sleeps with one of those apnea masks on (not sure why she would need one BEFORE they've figured out whether or not she has apnea), Kumar and Taub check out The Boob Lady's CT scan, looking for a possible diagnosis. All Taub can come up with is that The Boob Lady's plastic surgeon did a bad job and she's lopsided. Then he notices that their actual patient has flatlined. Oh wait -- she hasn't. She just decided to leave. I guess I wouldn't want to sleep in that bed either, knowing that Chase and Cameron went at it in there once.
They find Emmy running on a treadmill. Where did she find that? How did she get all that crap off her head so quickly? They glue things all over you during sleep tests -- it's not easy to take them off. And why did she think a nightly jog was a good idea, especially knowing that her doctors are trying to monitor her fucking sleep? Kumar and Taub order her off of the treadmill, reminding her that the last two times she exercised, she stopped breathing and stuff. Emmy thinks this time will be different. Emmy is a moron. She feels so good, in fact, that her broken ankle doesn't even hurt, nor did she notice that it's bleeding. Girlfriend is a mess. It looks like one of the metal bars from her ankle brace is cutting into her leg, so, way to fit that properly, PPTH. Taub sticks a needle in Emmy's leg, but she can't feel that, either. It starts to occur to Emmy that this might not be such a good thing. If she can't feel her leg, how is she able to jog on it?
It's late at PPTH, so Hadley and Foreman are done with the trial and back in action. Taub tells House that the numbness is ascending up Emmy's leg. House is more concerned about how Emmy was able to sneak out of the sleep lab without them knowing. Kumar lies that Emmy said she wanted to use the bathroom. What sleep lab doesn't have a bathroom in it? Methinks the writers should have done a little sleep lab research. Anyway, Kumar says the testing they were able to do on Emmy ruled out the apnea (a few hours of sleep with a C-Pap on? Not really), and then they're in House's office, where Cuddy is pouring hydrogen sulfide all over the floor. Wikipedia tells me that hydrogen sulfide is the reason why rotten eggs and farts smell, so this is not a pleasant experience for anyone. Except for Cuddy, who says she's sure the smell will dissipate by tomorrow morning. That's good for her, since she's leaving now and won't be back until then, but House will be pulling an all-nighter. Ha ha ha! But stupid, Cuddy. Very stupid. He's not going to take that lying down.
