Samples for the Doctor

One day an old man got really sick so his wife went to the doctor and told him that her husband had a lack of energy, a cough, and couldn't get an erection. The doctor said that there was nothing that he could do until he had a stool, urine, and sperm sample from the man.

When the old woman got home to her husband, he asked, "What did the doctor say?"
She responded, "He wants a pair of your underwear."
