How about a game of exquisite corpse?

Background

Excerpted from the MoMALearning article linked here: Surrealist artists played a collaborative, chance-based parlor game, typically involving four players, called Cadavre Exquis (Exquisite Corpse). Each participant would draw an image (or, on some occasions, paste an image down) on a sheet of paper, fold the paper to conceal their contribution, and pass it on to the next player for his contribution. [...] For the Surrealists, Exquisite Corpse was a perfect parlor game, involving elements of unpredictability, chance, unseen elements, and group collaboration—all in service of disrupting the waking mind’s penchant for order.
