A rottweiler, pit bull, and chihuahua were working construction when a female collie walked by. Noticing their cat- calling she replied, "I tell you what, I like cheese and liver. If you can say something with those words in it, that I like, you'll win a date."
The rottweiler began, "Liver is good and cheese is better, just like us, they belong together."
Then, the pit bull, "We are alike, I like liver and cheese, and even better, I do not have fleas."
When the chihuahua's turn came, he turned towards the other two and said, "Liver alone, cheese mine."
