Steve Valentine, who plays Flynn, is also a professional magician in real life. See more »


Foreman explains that the patient had antibodies for blood type A and type B and that the blood banks test for antibodies and that this is why they wrongly deduced the patients' blood type. In fact the blood banks test for both antigens and antibodies, eliminating the possibility for this error. On top of that, a patient with antibodies for both blood types would be shown as having type O. See more »


Dr. Gregory House: You eat a lot of beets. You have an electric toothbrush, and you sleep less than six hours a night.
Flynn: That's impressive.
Dr. Gregory House: The red betanin from the beets stains the plaque deposits on your teeth, which are then swirled by your spinning toothbrush. Your heavy lids and your prematurely aging skin tell me that you're carrying a major sleep debt.
Flynn: That was way cooler before you explained it.

Tricky doings
24 November 2007 | by (Connecticut) – See all my reviews

A magician (Steve Valentine, late of CROSSING JORDAN) almost drowns during the Houdini water tank trick and Mormon Guy and Punjab happen to be on hand to rescue him. House is not convinced the guy's really sick, which leads to some interesting bits of business. Meanwhile, House dreams up a ridiculous scheme to eliminate the next team candidate. It involves Cuddy's underpants, of all things. And we finally get a glimpse at what makes 13 tick -- or not, as the case may be. She's convinced she is dying of an inherited disease while House is equally convinced she is not. Enough going on for you? Valentine, a veteran movie and TV actor, makes a great guest star, and the business about Cuddy's unmentionables ends up being a bit of a shocker. Maybe not the finest, but a very good HOUSE episode.
