"How did you know I passed you?", my friend asked. "Are you not blind?"
"I am not blind," replied the man, pointing to the dog. "Its Rover that is blind".
On closer inspection, we realised that the "To whom it may concern" tablet hanging from the man's neck did indeed say that one "Rover Donalds xxxxxx was blind from cataract".
Nigerians! What wont we do for money?
