Or how about this?

APPENDECTOMY – COUNTRY STYLE
Oscar Brand

Wash your hands and get them dry.
Keep them clean and keep them high.
When you're sure that you are able,
Promenade up to the table
And get that appendix, lay it bare.
We're doing the McBurney Square.

Now drape that patient neat and tight.
Bare the quadrant of the lower right.
Do si do and careful all,
While you make an incision in that wall.
Right hand under, if you dare,
Doing the McBurney Square.

Swing that knife blade with a toss
Along the muscles, not across.
With your fingers then induce
The peritoneum to work loose.
You mustn't rip and you mustn't tear,
Doing the McBurney Square.

When the cavity's been breached,
The secum and appendix reached,
Put a purse string suture on the base
And sprinkle gauze pads round the place.
Duck for the oyster, I declare,
Doing that McBurney Square.

With a peritoneal cuff inside,
Crush, ligate, and then divide.
Swing your partner; I'll swing mine.
Paint the stump with iodine.
Now force it back again with care,
Doing that McBurney Square.

Tie the purse string very tight.
Suture the peritoneum right.
Let those muscles settle in,
Then count the pads and close the skin.
Salute the patient; collect your fee.
You've done the appendectomy.
