Get a group of friends together and hit your town’s cultural hotspot: a museum, a gallery, a stately home, an architectural wonder, the seat of government. If you don’t have anything approaching a cultural hotspot, go to Safeway or a car yard instead. (In fact, that’s an even better idea…)
Take turns playing tour guide: use your imagination, speak loudly, and whatever you do don’t include a single accurate fact. Talk, talk, talk! Hold up an umbrella so no one gets lost. You know you’re really doing well when strangers start joining in (if you’re feeling very ambitious, you could advertise your free tour in the local paper). Points are awarded for style and plausibility.
