[spoiler]After being cut off by Darth Vader, Luke's hand found itself falling to the bottom of Cloud City. However, it survived by walking on its fingers and managed to make it to a landing platform where Lando Calrissian still kept an old ship of Han's around--the Millennium Fist (an obvious parody of the Millennium Falcon with a pair of green gloves stuck to the front). Traveling on the Fist, the hand arrives at Hoth to hook up with the Rebel reserves at the old rendezvous point. However, instead of the reserves, Luke's hand encounters the hand of the wampa that he previously fought on the icy planet. Luke's hand uses the Force to grab a nearby lightsaber and finishes off the wampa’s remains. The hand then returns to the Fist and speeds to the secondary rendezvous point—Tatooine. Luke’s hand goes to the Mos Eisley Cantina (where all the occupants are just hands like him), and encounters and defeats the hand of the Aqualish thug Ponda Baba. Unfortunately, Luke's hand next has to face the hand of Darth Vader. Despite fighting valiantly, Luke's hand loses and is frozen in carbonite. Darth Vader's hand then journeys across the galaxy into the heart of the Imperial fleet with Luke's frozen hand. The hand is defrosted and presented to the hand of Darth Vader's master--the "Emperor's foot" (though Emperor Palpatine perished at the second Death Star, his foot survived). The Emperor's foot attempts to turn Luke's hand to the dark side of the Force. However, Luke's hand once again refuses to be turned and the Emperor's foot attacks him with the Force, causing Luke's hand to lose its thumb. Vader's hand turns from the dark side just in time, and with help from Luke's hand, throws the Emperor's foot down a nearby shaft, killing the foot and defeating the dark side!

Oh yeah forgot about that. [spoiler]*slow claps*[/spoiler]

Obviously that isn't what really happened. His hand was found and used to make a clone named Luuke.
