I haven't seen
chimerism
on other mystery shows but surely many people saw
I Am My Own Twin
on Discovery Health. I thought it might be a solution from the ads, so I was surprised when it actually turned out to be the ultimate diagnosis.
ETA: I guess it was on CSI recently. (xpost with msbelle)
CSI, I think
And the Venture Brothers! Sort of.
Also on Grey's Anatomy, IIRC.
Plus, they never explained
how the titanium got in his neck
!!! Very sloppy writing.
The medicine was sloppy, but I thought the dialogue was fantastic.
On House
I just consoled myself with "he's not doing the brain surgery, just the diagnostic poking portion, there is a brain surgeon there we are not seeing." Wasn't the titanium from the pin he had in his arm when he broke it or the scalple he stuck in his neck?
That was the theory about
where the pin came from,
but it was never proven, and seems extremely unlikely.
