  1. Fallout 3 Official Game Guide Game of the Year Edition p.62: "Bill Foster
    Mr. Foster is a technician down at the local RobCo Plant. Always ready with a Sugar Bomb for the kiddies, he's a chipper sort, and prone to whistling, or impromptu bursts of patriotic sing-songs. He is most definitely not living a life of quiet desperation."
