is a short playlet written in 1931 by George Bernard Shaw which satirises a dispute between two doctors about the use of antiseptics in surgery.

Shaw regularly attacked conventional medicine in his works.

Cheyne and Wright are portrayed ridiculing one another's opinions.

He concludes that when doctor's disagree, no-one is harmed, but "when doctors agree we are face to face with a conspiracy of pretentious ignorance with that sordid side of trade unionism which is forced by common need to struggle for its livelihood even to the point of saying, 'Thou shalt die ere I starve'.

[3] However, here, Shaw, in line with his own belief in preventive medicine gives much more weight to Wright's views.
