It turns out that Cameron's advice to 24 was to get a jar of bugs and make them bite the POTW, then test the bug's stool for parasites. This is even better than testing the patient's non-existent stool, since the parasite will be more concentrated in the smaller bug poop. Unless the bugs have parasites of their own. Meanwhile, I had no idea that bugs pooped. I mean, I guess they'd have to, but I never thought about it until now. And now that I have, that's so gross. 24 starts the bugs a-biting, but POTW immediately starts coughing and going into respiratory arrest. 39 tells 24 to get the bugs off of him, but she refuses, since she's not done with her test yet. Her test won't matter at all if the patient is dead before the bugs can crap out some parasites. Even POTW's dog is annoyed and barks at her. Finally, 39 physically pushes 24 off the patient and attends to his choking problem.
But it's all worth it, because after the break, POTW is getting a nice back massage. House has called everyone back into the classroom for this new symptom where the patient's throat thinks his lungs are his stomach. That's what he said, people. I don't get it any more than you do. House asks the room for suggestions, but no one wants to give away any answers to the other team, because the job is more important than a patient's life. So House has to actually call on people, and starts with the Number we know isn't going to make it, so whatever, who says POTW's symptoms are "exotic" and therefore must be connected to his trip to Thailand. It turns out that the Number, whom House nicknames "Grumpy," was with Doctors Without Borders for eight years. House asks him why he wants a job that will keep him stranded in New Jersey now. It turns out that Grumpy is recently engaged and trying to settle down.
