Eight-year-old Benny's father took him to the zoo one afternoon.

The boy asked his father all kinds of questions about the various
animals they visited.

They eventually came to the fenced-in preserve where they kept the
lions. The father was explaining how ferocious and strong the lions
were. Benny was hanging on every word.

"Daddy," he asked, "If a lion ever jumped over that fence and ate you up..."

"Yes, son?" the father said.

Benny added, "What bus should I take home?"
