The issue of associations.
A few years ago, my friends bought a new car. One day, they had a shutdown. It had to be repaired, but I did not want to, because the car was impressively ripped. All the flat puppets on the pelvis stopped at the lights and asked "how did you get such a clear sound?" A friend had to be very silent and smiling, hiding the true cause.
We went to the village with relatives. Upon returning to the city, the extinguisher was repaired the next morning, immediately.
The secret is the following. As they walked around the village, they were jumped out of every house to meet them. At first, the friends were surprised and could not understand. And then the good grandfather explained to them that with such a sound they were driving the "gentleman" - the most disgusting, stinking and robbed tractor, which pumps the shit out of the septic. People are always looking forward to him with joy.
