So simple yet so effective. We just never stop to think that Vader may very well have a life just like that of our own. I mean sure he’s an evil dictator who instills fear in his Stormtroopers. And yes, he kills by simple use of the force.
But does he not go to the bathroom? Does he not eat? Take a shower? Things we never seem to think about with our Dark Lord Villains. And you know that he would never stoop to squeezing his own oranges in the morning.
The death star bowl is a nice touch.
