A elderly couple visits a doctor

An elderly couple visits a doctor.

The doctor says to the old man, “I’ll need a urine sample, a feces sample, and a blood sample.”

The old man says, “What?”

The doctor repeats himself.

Once again the old man says, “what?”

So the doctor yells it,

“I NEED A URINE SAMPLE, A FECES SAMPLE, AND A BLOOD SAMPLE!”

With that the old woman turns to the old man and says,

“He said needs a pair of your underwear!”
