here is one
A Chihuahua, a Doberman, and a Bulldog are in their local doggie bar having a few cold ones when a good-looking female French Poodle walk in the bar and walks 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 French Poodle 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!"
