He also leaves all of PPTH, in favor of the boxing gym Foley trains/works at. Apparently, losing a match puts you on janitorial duty, as Foley is mopping the floor when House arrives. House says he has "good news" for Foley -- he now believes Foley has a neurological condition called "sympathetic overdrive." Foley ignores him in favor of cleaning the floor, but House persists, saying that Foley can go back to winning bouts instead of losing them. Apparently, Foley won his first 20 bouts but lost his last 5. And Foley doesn't think he has a problem? He asks House why the $50 he lost on Foley is such a big deal. House says it's about more than the money -- it's about "dignity." For both Foley and House. I think for House it's more about "not being wrong, especially not to Wilson" than dignity, although that's probably the same thing to House. Foley seems to be listening, so House grabs his arm and injects him with some epinephrine to test his theory. Foley is not happy about this, especially when it turns out that House was using the epinephrine to induce a tachycardic heart rhythm in Foley. Once he's accomplished that, House starts punching lightly at Foley, believing he'll pass out like he did in the match. But he doesn't. House keeps punching at him until Foley loses his patience and tosses him to the floor. He still hasn't passed out after that, so he calls House a lunatic and tells him to leave him alone. House doesn't seem to mind being tossed to the floor as much as he does being wrong about Foley again.
