"Name the Baby" joke

This young woman brought her child into Children's Hospital
for a routine check-up. On the records, the nurse saw that
the child's first name was Urine (pronounced Urin-ie). Not
wanting to be rude, but wanting to know why this woman would
name her child this, the nurse asked her how Urine got her name.
The woman explained, "Well, my baby was born premature and had
to stay in the special nursery. She was real sick and they
didn't know if she would make it. I couldn't decide what to
name her, but the nurses said they would pray for her. One
day I came in and there was this paper on her incubator that
said 'Please save Urine', so I knew that they had named my baby."
