If Rambo had been in Custer's command, Errol Flynn would have faced an entirely different challenge making up history. Driving around in a stolen Guard truck or Soviet tank, Rambo would have slaughtered Big Cloud and the rest of them, ensuring America's safety from illegal aliens.
John Wayne wouldn't have died fighting sea bees. Rambo would have shown Washington's troops how to make winter gear with a knife, old rope and a tarp. They would have waded across the Delaware before machine gunning and blowing up mercenaries.
If Rambo had been Thomas Edison we'd have extremely lethal lightbulbs. As Doctor George Clooney, he'd have a compass and fishing gear in his scalpel. And the look on his face . . .
I can't see Rambo playing Bing Crosby pretending to be a priest and he couldn't have played patty-cake with Bob Hope. If Rambo had been James Bond pretending to be Perry Mason, Della's clothes would have fallen off all the time.
Can you imagine if Moses had really been Rambo? Would he have threatened the pharoah? You bet. Called in an airstrike or filled the Nile with Egyptian blood. Rambo would have been a great Samson but he wouldn't have died like Victor Mature. Probably would have worn a tarp, though, around his waist.
Rambo one of the Monkees? It's possible. Could he have hosted a game show? He could have done some damage on Family Feud.
