The Lone Ranger, while hunting down some low-down-murderous scum, is captured.
Fortunately, Silver escapes. The bad guys decide to take Loney out into the
desert and tie him down, naked, to stakes. Once they are satisfied that he is
secured, they leave him to die slowly.
Silver appears at the scene. The Lone Ranger says to him, "Silver, go to town
and get the posse!" Silver rears back, whinnies, and charges off to town,
many miles away.
All day, in the blistering sun, the Lone Ranger survives. Just as he thinks
the end is near, night falls. Though relieved at first, he begins to get
colder and colder. By sheer will power, he manages to survive the night.
As dawn breaks, he hears the thundering of horse hooves. Up gallops Silver
with a naked woman on his back.
"Goddammit, Silver, I said 'POSSE'!!!"
