Little Johnny wanted to go to the zoo and pestered his parents for days.
Finally, his mother talked his reluctant father into taking him.
After several hours, the two men of the family come back, smiling and tired.
"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!"
