Mr. Geography
When taking a cab back to my friends in Toronto where I stay, I got Mr Geography as a driver. This guy starts by asking the customer a question, and if one can answer the question right, you get a free cab ride. The question I got was: What is the capital of Chad? Unfortunately I did not know the answer, so I had to pay the ride.
On the other hand, he did not know where Glenview Avenue was, so I had to read the map for him the last couple of blocks…
