It's not lupus, no, it's gangrene.
That's why your leg has turned the color of the leaves.
And I think it could be dire
if it's red, or yellow, or gold
or something much more colorful like that.

It's not lupus, no, it's gangrene.
Your symptoms show up as so many other ordinary things.
If lupus, we could pass it over
'cause it doesn't stand out
like fleshy chancres on your privates
or cysts in your eye.

Gangrene is so easy to treat.
And we may not have to amputate.
My bill will be big like an ocean
'cause my ego's like a mountain
because I'm House, M.D.

Gangrene is all I thought 'twould be
but now I have to wonder why.
Why'd I blunder, I blunder?
Not gangrene.
It's lupus, fine!
Prescription's filled!

And alone is what I want to be!
