Shortest play in world drama

Samuel Beckett (1906 - 1989), author of the most infuential play in post-war drama, Waiting For Godot (1953), also wrote the shortest play in world drama, the 30 second Breath (1969).  First perfromed in 1970,  it is set on a stage scattered with rubbish and off stage someone cries out.

'Faint brief cry and immediately inspiration and slow increase of light together reaching maximum together in about ten seconds. Silence and hold about five seconds.'
