This improv game is in the following improv game categories:
Technique for building/advancing scenes. To be used sparingly.
The idea is that any player can stop the scene by yelling freeze, step out of character, and
describe something within the scene, without interrupting what is going on in the scene. After
nthe comment, player unfreezes the scene and steps back into character.
Example. 2 players in a scene where a backpacker is looking for a bed at a house where an
old lady lives. Backpacker comments on the fact that the house is chock full of stuffed animals,
an little pictures of backpackers, thereby implying that the old lady kills and stuffs backpackers
(idea stolen from a short story by Roald Dahl).
