Two old people, a man and a woman, walk into a hospital.
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?”
So the doctor says it again.
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 needs a pair of your underwear!”
