Limericks are a tough guy

"Sher from the Shire"

In a hovel of three lived a Sher,
Whose idling days were a blur
Due to the haze
Expelled from his j's
He often di'n't know where he were

And so on and on, daily it went
'Til one day a message was sent
"You are to report
To a neighboring fort,
With a clean bill of health." Oh! Lament!

Frantically, Sher went a-searching
For a potion intended for purging
The crud from his pee
And we'll shortly see
If the potion indeed's really working
