And here I thought we were going to see some test named after, like, Mark Bagelle, or something, or maybe it was spelled "B.A.G.E.L. test," where the letters all stood for something scientific. Nope! The bagel test involves actual bagels. And speed-walking on a treadmill while eating them. Biana tries to convince us that this is medically relevant by saying that high carbs plus exercise is the fastest way to confirm their diagnosis of Thyrotoxic Periodic Paralysis. Basically, they're trying to set him up for another bout of paralysis. But it's been a half an hour and he's still moving, which is kind of admirable in and of itself when you consider that he has liver failure and that eating while exercising causes the worst stomach cramps. Kumar steps aside to answer his phone, only to hear House on the other end saying that the bagel test isn't working. Kumar looks around suspiciously for the House he's sure is watching them, and then House tells him to stop looking around suspiciously. "You are completely predictable," House says, and Kumar looks both disappointed that House doesn't have awesome psychic abilities and sad that House criticized him. House wants to hear Driver's breathing, but he's interrupted by the nurse, who very much doubts his story that he's just in the bathroom to take a dump. Maybe it's because she can hear him talking. Or because she just noticed her awesome pink cell phone is missing. House tells Kumar he can hear Driver's "labored breathing" and the nurse bangs on the door and yells at him. And then Driver collapses, so Kumar cries out that the test worked. But House hears Driver wheezing and says he can't be paralyzed if his chest muscles are working. As for what's really wrong with the guy, House says, he can't figure it out without being there.
