3 surgeons decided to go for a camp and hired a guide for assistance. Over campfire , they met with an accident and the guide got seriously injured. The guide needs surgery(a minor one). The 3 surgeons decide to operate but they have only two medical gloves. To save the guide , all three surgeons are needed to operate on the guide, in sequence.
How can this be done without any of them being exposed to the blood of any of the others?
The first surgeon operates with the first glove (glove A) inside the second glove (glove B). The second surgeon operates using just glove B. The third surgeon operates using glove A, turned inside out, inside glove B.
