On House, MD, there was a running gag were for every case, someone would suggest that it could be a specific disease but it never was (I can’t remember if it ever turned out to be the case).
I knew it not to long ago, but seem to have completely forgotten it now. I keep wanting to say polio, but that doesn’t seem to be right, and Googling it is not turning up anything because most people don’t bother with the “MD”, so searching for
house "it could be" or even
house md running joke "could be" aren’t very helpful.
What was the disease that they always suggest it might be? Bonus points if you know if it ever turned out to be correct.
