The Taco Bell Chihuahua, a Doberman and a Bulldog are in a doggie bar having a drink when a good-looking female Collie comes up to them and says, "Whoever can say liver and cheese in a sentence can have me."
So the Doberman says, "I love liver and cheese."
The Collie says, "That’s not good enough."
The Bulldog says, "I hate liver and cheese."
She says, "That’s not creative."
Finally, the Chihuahua says, "Liver alone, cheese mine."
