Round One:
We find ourselves in a "What-If" universe, which is an alternate universe where one single difference changes the course of human history. In this case, we find ourselves in a scene from The Last Crusade where Indy, in the guise of a Nazi soldier, encounters Hitler at a book burning. As per the movie's events, Hitler signs Henry Jones' journal, not realizing how important it is. Indy stares at Hitler, baffled and thanking his lucky stars that his cover hasn't been blown.

Then he asks himself, "Who gives a damn about my cover?" Pulling out his pistol, he shoots Hitler at point blank range, killing him dead. Round One goes to Hitler.

Round Two:
While Indy makes his daring escape, killing several soldiers on his way out and rescuing at least one damsel in distress, Hitler's corpse is immediately rushed off to a hidden chamber deep beneath the streets of Berlin. There a group of Satanic priests begin an ancient ritual to bring life back into his unmoving bones. Within the hour, Hitler walks again as a zombie and the Third Reich is seemingly saved.

Unfortunately for the Nazis, death has provided a rare bit of clarity for Hitler, and he sees how he has wasted his life up to this point. Hitler immediately goes back to his first love: painting houses. Meanwhile, Indy foils the Nazi plot to recover the Holy Grail, and the Allies later bomb Germany into submission. Hitler is left forgotten and undead but happy nonetheless, spending his time somewhere in the fields of Austria, painting a barn. Round Two goes to nobody.

Round Three:
It is a well-known fact that zombies make terrible house painters. They are too slow, have poor work habits, and tend to devour their employers for their tasty brains. Hitler proves to be only average as a zombie house painter, and thus soon finds himself out of work. Crushed by this turn of events, his undead mind becomes consumed with the desire for bloody vengeance against the man responsible for his zombified state.

However, Indy was wearing a clever disguise when he killed Hitler, and so poor Adolf doesn't know where to begin. He wanders around aimlessly for quite some time. Then, by chance one day Indy comes across zombie Hitler on a routine archaeology expedition. He pulls out his routine archaeology equipment, which of course includes a flamethrower to fight off those pesky undead with a craving for human flesh. Hitler is incinerated by the cleansing fire, and some nameless muse sheds a tear for the sweet zombie painter that never knew happiness. Round Three and the fight go to Indiana Jones.
