Cardiovascular Incision

I am the surgeon, and here is my knife;
let's open you up, see what's causing your strife.
(Please don't regret trusting me with your life.)

Oh I am the surgeon, and here is my table.
Climb up and I'll help you heal, if I'm able.
(Don't mind if my hands are a little unstable.)

Sure I'm a surgeon, see, look at my tools!
But the people who ask me for help are all fools.
(They should teach more heart surgery in schools.)
