A lady came in for a routine check-up at her 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!”
