Okay so I'm watching the second Star Wars (The original) and we came out with this idea.
Vader sat patiently in his chair awaiting his cup of tea (hey sometimes Vader wants tea too) when a storm trooper walked nervously towards him, a cup of tea in one hand.
"Your tea my lord" He said shakily.
Vader accepted the tea without saying anything, he took a sip as the stormtrooper stood as professionally as possible, although you couldn't make out a facial expression, Vader could feel the fear emanating from him. He placed the cup down carefully on the table and looked at the stormtrooper.
"Sir?" He questioned.
"There's two sugars in this"
There was a silence, then the stormtrooper gulped.
"I'm...sorry?" He questioned again.
He stood up and spoke again.
"There's two sugars in this" The sound of Vaders breathing was the only other thing to be heard.
Suddenly the stormtrooper began choking.
Vader walked towards him.
"I only take one"
"I'm...so..rry"
"I know"
The Stormtrooper fell to the ground as another one walked in with a cup of tea.
"Your tea my lor-
his sentence was cut short as he stared at the dead stormtrooper in front of him.
"Oh...That's the new guy...we didn't think he would fall for the two sugar thing.."
"No trouble" Said Vader
