Sense Sonnet - Steamer

Extras

I am flying a commercial flight.
The extra charges blow my mind.
An extra charge for weight and height.
An extra charge if deaf or blind.
If I speak, then I'm charged per word.
If I itch then I'm charged per scratch.
If I poop, then I'm charged per turd.
Sneezes are charged 3 to a batch.
And extra charges are assessed
By the amount of body hair.
Depending on the size of chest,
I'm charged extra for breathing air.

And if a plane crash is my fate,
An extra charge to my estate.
