Clinic: Test

Two guys were sitting outside a clinic.
One of them was crying like anything, so the other asked,
"Why are you crying?"
The first one replied, "I came here for blood test"
Second one asked, "So? Are you afraid?"
First one 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 other,
"Why are you crying?"
The other replied, "I have come for my urine test."
