Guard #1: Man, about freakin' time!
Driver of pizza delivery ship: Haaaa.. kkkkkk... here is your pizza. Double cheese with pepperoni and sausage. May the force be with you.
Guard #2: Wha.. Lord Vader?! Is that you?!
Vader: Yes, I'm afraid. The Jedi have forced us into an ecomonic depression, so I needed some extra cash on the side. That will be 26 galactic credits.
Guard #3: Here you go, Lord Vader. Give our best to the Emperor.
Vader: What.. no tip?!! (uses force to strangle guards)
