Two guys were sitting outside a medical clinic. One of them was crying, tears were pouring down his face.

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

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

The second one asked, "So? Why are you crying? Are you afraid?"

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

Hearing this, the second one started crying.

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

Then the second guy replied, "I have come for a urine test."
