i, i, i, give in. We must have it. I once had a co-worker who barked Jingle Bells around this time of year. Now wouldn’t it be more appropriate to play Jingle Bells with your i-Dog and thus free yourself from any reliance on barking colleagues? Actually, i-Dog doesn’t really bark the tunes, but he does amplify whatever music you hook him up to and he dances to the beat. He (and his cousins i-Fish and Hip Hop Pig) joins a proud line of jiggling gadgets, walking stuffed animals, talking creatures and singing fish (remember those?) that supply us with cheap thrills while sitting around the house at Christmas time.
