For about a year and half now, Dr. Robert Jarvik, inventor of the artificial heart, has been a paid endorser for the cholesterol-lowering drug Lipitor. Pfizer keeps using Jarvik despite his being branded a “fop” who goes over like a lead balloon by the all-powerful John Mack. He’s also been called “Gollum-y” by Dr. Michael Eades. And NBC has questioned whether his medical credentials are all they’re hyped up to be. But there’s something else that bugs us about Jarvik’s commercials: the audio track. Is it just me, or does it sound like Jarvik’s lines have been dubbed over later rather than recorded along with the video? It’s creepy.
