An elderly couple walks into the hospital. The doctor says to the old man, “I’ll need a urine sample, a feces sample and a blood sample.” “What?” says the old man. So the doctor says it again, and once again the deaf old codger says, “What?” So the doctor yells it: “I NEED A URINE SAMPLE, A FECES SAMPLE, AND A BLOOD SAMPLE!” With that, the old man’s wife turns to her doddering husband and says, “He needs a pair of your underwear, darling!”
