Dormatron was an exercise equipment advertised in Grand Theft Auto III. It uses heat to exercise you while you sleep and "burn those pounds away". You strap it on your arms and legs, set it to 11, and it exercizes you while you have a good night's sleep. An advertisement can be heard on Double Clef FM and is mentioned on Chatterbox FM. The lady on the commercial says that she prefers the Dormatron over exercising and eating right, and states that "fat can ruin a relationship".
