(For Sherlock) What kind of locomotive do you prefer? Who is your favourite Spice Girl? Have you and Sherlock ever travelled internationally to solve a case? Archie, what is your favourite park? Have you ever smoked cigars? What is your biggest fear? Would you rather find 1000 cockroaches or a person in your basement? You're on a game show and you're given the choice of 3 doors. Behind one door is a car, behind the others, goats. You pick door nr 1, the host opens nr 3, which has a goat, and asks if you want to pick door 2. Should you switch your choice?
