Sense Sonnet - Pumper

On Call

At last I'm getting some good press.
To be an appendix has not
Been such a joy, more or less.
Useless thing - I've heard that a lot.
But now, I'm called the cul de sac
Where good gut germs can safely thrive.
It's said I have a reboot knack
For helping the bod stay alive,
When there's no outside source around,
Like other bods with healthy germs.
Someday, disaster may abound.
My host will need me on my terms.

Ready to serve - this appendix,
In upcoming epidemics.
