Marabout, piece of twine, saddle horse... A linguistic principle applicable to playwriting. Explanation: a first author begins the piece, a second continues, a third also. And so forth. This is not a room in sketches, but a story continues, with a beginning, an end, and even a medium. And when we discover the collection of funny writers who wrote the thing, we understand that we are not going to bother with this story of poor people trapped in an underground train, the evening of the new year. But at the bottom, why Juke Box? Because our friends are stuck in a box and music play a role (theatrical).
