A story from my dentist.
At school we had an all-known teacher. Do you know experts in all fields? Whatever the conversation does not touch, he with the smart look of the expert enters the conversation and begins to teach how it is done.
Once he gave a master class in the stomach clinic on the topic - "Making a blind." The material was gips then. He insisted in a few minutes. It was necessary to show when and how to remove the blindness.
The lesson was given on a random patient. Our omniscient got a piece of plaster in the poor man’s mouth and demonstrately went out to smoke. We waited the first five minutes calmly. For the next five minutes we started to worry. After 15 minutes, our patient began to shower. After 20 we have already tried to pull out the plaster ourselves, but in vain. Within half an hour we ran to find our teacher. The patient has already swallowed.
We found our teacher in the hallway. He showed the worker how to stain the wall!!!! to
