Stupid Joke

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 daddy have a good time?" asked his mother. "Yeah, daddy really liked it too" exclaimed Little Johnny "especially when one of the animals came home at 30 to 1!"
