A six-year-old boy was standing with his father in front of the polar bear enclosure at the zoo.
His father was explaining how dangerous polar bears were and told him that, out of all the animals in the zoo, they were the ones the keepers feared the most.
After listening for a while, the little boy looked up and asked,
“Dad, what if the polar bear escapes and eats you?”
“Yes, son?” his father replied.
The boy asked,
“Which bus do I catch home?”
