Blind date
Blind date is a guessing game for three players.
The audience assigns roles to two actors - either historical figures, fictional characters or celebrities. Each actor is out of the room when the other recieves their role, so neither knows the other's character.
In the scene, the actors dine together on a blind date. They ask each other questions and reply with hints as to their identity. When an actor guesses the other's character, they should mention the other's name, as though they knew the name throughout the meal.
The third character is the waiter or waitress and can drop their own hints if the actors take too long guessing. Off-stage actors can come on as other diners to provide additional hints as well.
The main problem with this game is that when you ask audiences for "historical figures," their minds return to the "My First Book of Biographies" they had when they were eight, and they end up picking names from a very short list. In theory, improvers should find it easy to act as Lincoln or Genghis Khan again and again, but in practice, the repetition saps their enthusiasm and hurts the performance.
