Meanwhile, Taub wants to test Danny. He tells Martha he's going to walk into Danny's room with a little hockey stick pen and wait for him to tell him how much he loves hockey, too. He walks in and asks Danny how he's feeling. Danny says his arm still hurts. Taub whips out his hockey stick pen and writes a note in Danny's chart. Danny notices the pen and asks about it. Taub says his nephew bought it for him because he's such a big hockey fan. He waits for Danny to talk about how much he loves hockey, only for Danny to say he hates hockey. Martha holds in her laughter and gives Danny some pamphlets on shelters for mentally ill homeless people in the hopes that he'll take her up on them. Danny brushes them aside, though, because his arm is currently in a lot of pain. Martha and Taub assume he's talking about the burnt arm, but Danny says it's the other one this time.
House rolls up outside PPTH in something much bigger than a Segway -- a monster truck. I'm pretty sure those aren't street legal, but okay. He rolls out a rope ladder for the Cottages to use to get inside so they can do the differential inside House's ridiculous new toy. Over the sounds of House's stereo and the monster truck engine, they decide that Danny doesn't have schizophrenia after all, since the pain in his arm shows he's getting worse and the medication they gave him should have made him better. Foreman wants to test Danny's DNA for early onset Parkinson's, but House says there are plenty of other genetic diseases it could also be and testing will take weeks and therefore cut into House's honeymoon time, which is unacceptable. He says they just have to find Danny's parents and see if they have any genetic diseases, and then they'll have a good idea of what Danny has. Martha says Danny won't tell them who he is or who his parents are. House says that three doctors and one genius almost-doctor should really be able to outwit one homeless junkie. With that, the light turns green and he roars ahead. He doesn't go off a ramp and crush a bunch of old cars, though, so it's kind of boring. Not to mention he probably went through an entire tank of gas during that five-minute differential.
