Everyone thinks that Einstein was so smart. Let's examine this. What was his big contribution? Everyone knows that: the theory of relativity. This theory states that, when moving near the speed of light, everything is related. For example: say your uncle is moving at the speed of light. Then he is also my uncle. Also, our uncle, moving faster than the speed of light, becomes smaller and goes slightly back in time, to the moment just before he accelerated past the speed of light, at which time he goes back to his regular size. This can be a good or a bad thing, depending on the original size of one's uncle.
The other theory Einstein developed was Heisenberg's Uncertainty Principle, which stated that Einstein felt unsure about Heisenberg. Heisenberg responded with his famous Einstein's Annoying Theory, which stated that Heisenberg found Einstein hard to take. Some believe their dispute originated when Einstein tricked Heisenberg into travelling faster than the speed of light, thus decreasing Heisenberg's mass - and Heisenberg was already quite small. After Heisenberg came back from travelling at the speed of light, Einstein could hold him in one hand. And often did, to Heisenberg's consternation, causing Einstein to formulate his Heisenberg's Consternated Theorum. But history proved Einstein wrong, since there is no such word as "consternated".
The idea that mass decreases as one approaches the speed of light is compelling, especially for dieters. It implies that one way to lose weight is to run, briefly, at the speed of light. As stated above, the downside is one will also go back in time. So you'll be lighter, but may find yourself in the 1400s, when everyone was lighter, due to malnutrition, and no one will even notice you've lost weight. Also, due to your modern clothes, you'll probably be declared a witch and burned at the stake. On the bright side, post-burning, you'll achieve your lowest body weight.
Einstein once explained relativity like this: "If you're sitting on a hot stove for even a minute, it will seem like an eternity; but if you're sitting on a hot stove with a pretty girl, your ass will burst into flames and not a girl in the world will seem pretty. Trust me, I've tried it."
Part of Einstein's mystique was his tendency to wander around completely lost, hair sticking up, playing the violin. Heisenberg tried this but was too small, well-organised and balding, so ended up with neat hair, dragging his violin behind him, sure where he was. And hence Einstein is remembered as the greater genius.
