Duke

"honey, Duke didn't eat any of his food again--this is the third night in a row," cries the frustrated wife to her confused husband. After all, it was the loving couple that was supposed to get all the benefits by teaching the family dog to do back flips and letting him perform at the local carnival, right? Duke had other ideas, however, and now he spends his days "performing" for the next-door neighbors from the comfort of his own backyard, after which he always earns a share of the tasty hamburgers and hot dogs that have just come off of their grill!
