I have heard of history, even in the times of the Union.
Geophysicists in the taiga camp were destroyed, research conducted.
And for 2 bottles of vodka agreed with the drillers that they had two toilets of the type of "sorting". The drillers made two holes and left, and the top of the booth was wooden, all as appropriate. The man went to the wind, to try a new toilet - sat down, swallowed up.... the sound he heard after a long time.It turns out that the drillers did not shrink - the shurfs went to a depth of 50 m. People first learned - were afraid to go there =)))
