A blind man takes a stool sample to the hospital

Everyone is looking at him with disgust as he asks for the optical department.

"Sir the laboratory is to the right"

"I don't need to go to the laboratory"

He hops on the elevator and yet again is told the laboratory is to the right

"I don't need to go to the laboratory! I need the optical department"

Finally he gets there and the doctor looks at the sample and says

"Sir this isn't the laboratory"

The blind man out of rage then tells him

"I don't need the godamn laboratory! I need to go to the optical department because every time I do this my eyes get watery!"
