Old people, arent they cute?

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!"
