Two little boys were sitting outside a clinic. One of them was crying and blubbering to himself. Billy: "Why are you crying? " Bobby: "I came here for a blood test." Billy: "So? Are you afraid?" Bobby: "No, not now; it's over. But it hurt!" Billy (concern obvious on his face): "Why do you say that?" Bobby: "Well, for the blood test, they cut my finger." At this news, Billy's eyes shot open wide and he started to cry VERY loudly; Bobby was astonished. Bobby: "Why are you crying now?" Billy: "I came for a urine test!"
