Wadsworth

 is your personal Mr. Handy butler in Megaton, which you get, together with a house, for disarming the nuclear bomb that lies in the middle of the town. He can give you instructions on how to spruce up your house, give you haircuts and tell science-related jokes (only one at a time, so he can recharge his 'humor emitter array'). Wadsworth can also give you Purified Water, but only five at a time before needing to recreate his supply. It takes 7 days for him to recreate his supply.

His counterpart in Tenpenny Tower is Godfrey.

Trivia

 * The joke, "War does not determine who is right- only who is left." is a quote from Bertrand Russell.
 * His name could be a reference to Tim Curry's Character "Wadsworth The Butler" in the movie "Clue". In the movie "Wadsworth" is a rather cynical butler with a distinctive english accent much like the "Wadsworth" in Fallout 3.
