Put the elephant in the refrigerator and ask why there are three steps.

Putting an elephant in the refrigerator is the same as putting other things in the refrigerator. There are three steps:

1, open the refrigerator door;

2. put the elephant in;

3. Close the refrigerator door.

The first step is the premise of putting things in the refrigerator, because the refrigerator is closed except the refrigerator door, so it is impossible to put things without opening the refrigerator door;

The second step is the necessary link and the same purpose;

The third step is to save energy and protect the refrigerator. If the refrigerator door is not properly closed, the temperature in the refrigerator will rise, forcing the compressor to work continuously, thus increasing power consumption and damaging the compressor.

This problem stems from the sketch "The Hour Worker" performed by Zhao Benshan and Song Dandan.
