Back when I worked at the "Big House" (name hidden to protect the innocent), it was a place that encompassed Medical doctor training. Working in the ICU's, a nurse had to stand by, when those trainees, were doing all sorts of line-placements. Some of those blokes, didn't remember landmarks of anatomy very well. For example, when searching for the femoral artery, one is supposed to remember the following mnemonic: Nerve, artery, vein.
This poem describes my frustration, watching an untrained operator, poking around in the groin area, of some unfortunate male subject.

Back to School

Nerve, artery, vein, uh-oh
Be careful where you poke,
Your next testiculectomy
Won't understand the joke.

Nerve, artery, vein, oh darn
You missed again, you fool,
One more try and if you fail
You're going back to school.

Nerve, artery, vein, oh well
You missed it by a mile,
You'll be a great success at Burger Boy
With your attitude and smile.
