I read a story years ago and it's one reason why I've always wanted an African Grey. The writer had a Grey and a dog named Bowzer. The Grey enjoyed taunting the dog and (in the woman's voice) say, "Bowzer! Do you wanna go out? You wanna go out" and poor Bowzer would be clawing at the door to go out while the Grey laughed and laughed! He would also occassionally bark like Bowzer and laugh when Bowzer got yelled at. The owner would know she had been had! But the story that got me is when Bowzer became ill. He was dying and the owner was sitting on the floor with him with his head in her lap and crying. The Grey said, "Awwww, Bowzer bad boy?" That broke my heart and also gave a big insight into the intelligence and communication skills of these magnificent birds.
