Joe is Tony's sidekick and employee of Tony's Restaurant in Disney's 1955 film Lady and the Tramp and its 2001 sequel. He was voiced by Bill Thompson in the first film and Michael Gough in the sequel.
Joe carries a slender figure. He has both black curly hair and eyes, tan skin, lavender circles, thick black Italian-style moustache and thick matching eyebrows. He wears a white elbow-length shirt with each couple light gray horizontal buttons vertically on his chest, a white bandanna, a light gray apron, a pair of olive pants, a pair of brown low-heeled shoes, and a white chef hat. On their romantic evening, he plays his mandolin when he sings Bella Notte to Lady and the Tramp with his boss Tony, who plays his accordion.
While Joe is usually nothing more than a loyal employee, he can be annoyed by his boss' short temperament. Aside from this through and through he is loyal to Tony and enjoys the company of "Butch" (the Tramp).
In Lady and the Tramp, Joe is first seen when the Tramp stops by Tony's Restaurant to get a bite of breakfast, and when Joe sees the Tramp, he throws him a bone for breakfast. Later on in the film, when the Tramp brings Lady to the restaurant, Tony tells Joe to get the Tramp some bones. Then, when Tony sees Lady, he orders Joe to cook Lady and the Tramp a fancy dinner. When the Tramp tells Tony in dog language what he wants, Tony tells Joe that the Tramp has said that he would like spaghetti for dinner, to which Joe replies, "Tony, dogs don't talk." But when Tony says that the Tramp is talking to him, Joe says, "OK, he's-a talking-a to you! You the boss-a!" Joe then gives Tony the food, while muttering "Mamma Mia" in Italian, to give Lady and the Tramp. Then Joe and Tony perform the song "This is the Night" for the lovely dog couple. Joe plays the mandolin while Tony plays the accordion. Joe isn't seen throughout the rest of the film after this.Jim Dear, Darling, Junior, Lady, the Tramp, and their puppies a plate of spaghetti, but then, Scamp barks and jumps up excitedly when he sees the spaghetti which causes Joe to lose his balance and dump the spaghetti in Tony's face. Later on in the film, Scamp brings Angel to Tony's where Joe and Tony present them with spaghetti, just like they did with Scamp's parents in the previous film, but instead of them singing, Joe and Tony just watch happily as Scamp and Angel eat the spaghetti together, just like Scamp's parents did long ago. Joe doesn't appear in the rest of the film after this.
