Visit to a Zoo

Little Johnny wanted to go to the zoo and pestered his parents for days. Finally his mother talked his reluctant father into taking him.
“So how was it?” his mother asked when they returned home.
“Great,” Little Johnny replied.
“Did you and your father have a good time?” asked his mother.
“Yeah, Daddy especially liked it,” exclaimed Little Johnny excitedly, especially when one of the animals came home at 30 to 1!”
