Albert Einstein is regarded by many as being the most intelligent human being to have ever existed, but it seems that he had other aims and targets in life that he was not quite able to achieve.
Not content with managing to unravel a number of the mysteries of life and the solar system in general, it seems that what he really wanted to do was to become a plumber. There was just something about getting his hands dirty in those situations that really appealed to him, but he was too busy dealing with more pressing matters.
However, it seems that the local plumber’s association took note of this and upon hearing of his desire they quickly gave him membership to their association, something that he was apparently pretty proud of. For the sake of humanity, it was probably best that he did not follow through on the plumbing aspect though.
