There's three dogs, a Chihuahua, a Doberman and a Bulldog all sat in a bar having a quiet drink when a great-looking female Collie strolls in.  She comes up to them and says, "Whoever can say liver and cheese in a single sentence can have their way with me."

Quickly, the Doberman says, "I love liver and cheese."
The Collie replies, "That's not good enough."

The Bulldog says, "I hate liver and cheese."
She laughs and says, "That's not creative enough."

Finally, the Chihuahua says, "Liver alone . . . cheese mine."
