A man was in a hospital bed with an oxygen mask over his face. When the nurse came in to check on him he asked "Are my testicles black?"

The nurse said, "I don't know we didn't do anything that should affect those."

The man shook his head and repeated, "Are my testicles black?"

The nurse sighed and lifted his gown, checked the area and under the area, and said "No sir, your testicles are not black."

A confused expression crossed the patient's face and he pulled the mask off and said, "Are my test results back?"
