Picard is standing around waiting for Worf and Dr. Crusher on Celtris III. A transport rolls up and the driver asks for directions.

Stranger: “Hey Buddy, do you know where the dilithium crystal store is?”

Picard: “As chance would have it, I do. You take this road down about a kilometer and turn left.”

Stranger: “A kilometer? What-? Ok, do you know how many traffic control lights there are between here and the turn?”

Picard: “There are four lights.”

Madred walks up: “Oh, you’ll never get there. There are five lights between here and the turn.”

Picard: “THERE ARE FOUR LIGHTS!”

Stranger: “Ok, Ok, chill out… But I’m going to ask someone else.”
