The Twilight Zone Recap: Mister Denton on Doomsday
The town drunk is given a potion by a traveling salesman (conveniently named "Mr. Fate"), and instead of the trembling hand of the town drunk, he returns to the previous form of the fastest gun in the West. Only to recall why he crawled into the bottle in the first place - to avoid ending up dead in the gutter.
At the end of the episode, he meets another, younger, gun, shooting to become famous by taking out the fastest gun in town. Only the young gun also has the potion. They manage to shoot one another in the gun hand, leaving each other alive, but unable to fight any longer.
Notable because of the presence of one Martin Landau, and because it's just the third episode of the series. But that's about it. Otherwise it's slow moving, and a nice story, but there are many better episodes out there.
