Liver n' Cheese Poodle
There was a labrador, a dalmation and a doberman in a doggy bar when an attractive girl poodle walks in. She says to the three dogs "Whichever one of you can say the best sentence with liver and cheese in wins a date!"
So the labrador says " I like cheese but I don't like liver," but that wasn't good enough for the girl poodle.
Then the Doberman said "I like liver but I don't like cheese" but it still wasn't good enough.
Finally the dalmtion piped in with "Liver alone. Cheese mine!"
However, he still lost because it was the cheesiest joke she had ever heard.
