I love asking this one to people. It’s even better if you ask them to keep track with a pencil and piece of paper.
You’re driving a bus.
First stop: you pick up 7 people.
Second stop: you pick up 3 more and drop off 2.
Third stop: you pick up 5.
Fourth stop: you see that no one is there so you do not stop.
Fifth stop: you pick up 3 and drop off 1.
Now, What’s the bus driver’s name?
They usually look at you stunned and say “how am I supposed to know?”
