In a Catholic hospital,
The nun asked how he should be billed.
When he said he had no money,
He could tell that she wasn’t thrilled.

She asked if he had any kin,
“I have a sister you could dun,
But she like you is a spinster
With no money, she is a nun.”

The nun, he saw, got quite upset
“Don’t you know she’s not a spinster?
We nuns are married to our God.
That goes, as well, for your sister.”

That thought had not occurred to him.
It was an ‘out’ he quickly saw.
“If my sister’s married to God,
You can bill my brother-in-law!”
