A boy was standing in front of the polar

A six-year-old boy was standing with his father in front of the polar bear enclosure at the zoo.

The father was telling the boy how dangerous polar bears were and that, of all the animals in the zoo, they were the ones that the keepers feared most.

Eventually, the boy said:

“Dad, what if the polar bear escapes and eats you up…?”

“Yes, son?”

“Which bus do I catch home?”
