Five.

While Cinnamon creates a diversion by seducing the chief of staff, I will sedate the fascist dictator with gas in the elevator. Willie removes the unconscious body disguised in the laundry cart that brought Rollin in. Rollin will impersonate the dictator long enough for Barney to fly the hovercraft up to the tower and unscrew the old lightbulb. Cinnamon will have the replacement lightbulb in her purse, and we'll leave the dictator to face the firing squad for Rollin's actions while we all escape in Willie's laundry truck.

...IT'S RESEARCH I TELL YOU.
