Full disclosure, I have never dissected a frog.
In the diagram you are neat.
Lying symmetrical and straight
The incision like a slit
In pastry or perhaps felt.
Your organs tidily separate
Easily seen, their colours bright.
As if your reason to exist
Had only been to educate.
And now, here you are lying
Before me: stunned, pulsating
I drag the scalpel through your writhing
Flesh. Reveal the messy, heaving
Pile of guts. The odour rising
To my nose. The blood seeping
The strange, elastic membranes concealing
The clean, didactic image I had been expecting.
