A lady came in for a routine physical at the doctor’s office.
“Here”, said the nurse, handing her a urine specimen container.
“The bathroom is over there on your right.
The doctor will be with you in a few minutes.
A few minutes later the lady came out of the bathroom with an empty container and a relieved look on her face.
“Thanks! But they had a toilet in there, so I didn’t need this after all!”
