We're back in the farmer's hospital room, and House says they ended up giving him the antivenom. The Cottages have gathered around the bed, prepared for another allergic reaction. The farmer says he'd like to wait for his wife to get there before they give him the antivenom, and Foreman says they can't. You see, time is short once your leg starts to turn black. The farmer gets the drugs, and this time, he's allergic-reaction-free. House leaves the hospital room, only to run smack into the golfer -- still played by the middle-aged guy and not by Carmen Electra -- who says his leg hurts again.
"On average, drug addicts are stupid," House explains to the class as he dry-swallows some pills. StudentForeman says he'd call the cops at this point, but House doesn't agree. Even drug addicts can get sick, after all, and if your patient dies because you withheld treatment, you can kiss your medical license goodbye. House says there's another, faster way to weed out the actually sick druggies from the fakers: he likes to insert catheters into them without anesthesia, figuring that only someone who was in some serious real pain would be able to stand having a thick rubber tube shoved up his penis. House does not say whether this method applies to women as well.
