House M.D.2004

Joe Dugan:
Give me a percentage. What are the odds of this thing working?

Martha Masters:
There's an 85% chance that this will kill you.

Joe Dugan:
So you want to give me something that works 15% better than arsenic?

Martha Masters:
Technically. It works infinitely better because arsenic has a 0%... chance... This is your only shot. Both Dr. House and I believe that. He faked a blood test in order to get you approved for this treatment, and then, he tried to bribe me into lying to you about the risks. If either of these incidents came to light, he'd be suspended and probably lose his license.

Dr. Gregory House:
I'm sure some other people would suffer.

Martha Masters:
He's risking his career to give you this chance. He wouldn't do that if there was any other choice.
