Once there three male dogs who set eyes on a beautiful female poodle. They all rushed over to her. Aware of her charms, she said, "I will go out with the first one of you who can use the words 'liver' and 'cheese' together in an intelligent sentence."
Immediately the Lab said, "I like liver and cheese."
"No imagination at all," said the poodle.
Next was the muscular Rottweiler, who blurted, "I hate liver and cheese."
"That's worse than the Lab," she replied.
Finally a tiny chihuahua smiled at his opponents, gave the poodle a knowing wink, and said, "Liver alone, cheese mine."
