A police officer stops a car for speeding. "I'm sorry, but I have to give you a ticket. However, I won't fine you if you solve this riddle." says the officer. The man in the car accepts. "Okay then. It's nighttime, you're on a road and you see two lights approaching. What is it?" "A car", promptly answers the man. "That's too vague-", says the officer, "it can be any kind of car. I'll have to give you a ticket." "No!", says the man, "give me another chance." The officer agrees and says: "It's nighttime, you're on a road and you see a single light approaching. What is it?" "A motorbike", answers the man. "That's too vague-", answers again the officer, "it can be any kind of motorbike. I'm sorry but you failed again." "Oh come on! Give me a last chance!" says the man. The officer agrees again and says: "It's nighttime, you're on a road and you see two low and wide-apart lights. What is it?" "A truck", answers the man. But again, the officer says it's "too vague". So the man goes: "Considering that we're playing games, may I give you a riddle too?" "Okay" says the officer. The man proceeds then to tell: "It's nighttime, you're on a road and you see a flickering light. Close to it there is a young woman dressed in a revealing outfit. What is it?" "A whore", says the officer. "Too vague!", says the man, "It could be your mom, your sister, your wife..."
