Once an old couple went to a doctor. The doctor told the Old man than I need to conduct some tests on you. For that I need a feces sample, a urine sample and a blood sample of yours. The old man hears and says “What??” The doctor again repeats saying “I need a feces, a urine and a blood sample of yours.” The old man again asks “What??” The doctor yells on him this time saying “I need your feces sample, Urine Sample and a Blood sample!!!!” Than the old woman replies the doctor telling him that ” Doc! My husband need a pair of your underwear’s.”
