On your first watch, did you ever guess a diagnosis correctly?

I never have from the beginning. I was, however super proud of myself for getting one right before House said it.

S6E20 Spoiler:

When the guy who passed out at his wedding started lactating I suggested pituitary tumor, which they tested for so I get one point there. THEN when House started manipulating the guy’s neck I said Chiari Malformation (I have a mild one myself) and was actually right!
