Say liver and cheese and you can have me

A Chihuahua, a Doberman, and a Bulldog walk into a bar for a drink. A great-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 replies, “That’s not good enough.”

The bulldog says, “I hate liver and cheese.”

The collie says, “That’s not creative enough.”

Finally, the Chihuahua says, “Liver alone… cheese mine.”
