Two guys were sitting outside a clinic. One of them was crying uncontrollably.

The second guy asked, "Why are you crying?"

The first guy replied, "I came here for blood test."

The second guy said, "So? Why are you crying? Are you afraid?"

The first guy answered, "No. Not that. For the blood test, they cut my finger."

At this, the second one started crying.

The first one was astonished and asked him, "Why are you crying?"

The second guy said, "I have come for my urine test!"
