"The hardest thing in the world to understand is income tax." - Albert Einstein
Albert Einstein (March 14, 1879 - April 18, 1955) was a theoretical physicist. You've heard of E = mc^2 right? The Theory of Relativity?
Well Albert came up with it... one of the smartest dudes of all time and he can't even figure out his taxes. I don't know why he was spending all that time trying to figure out mass-energy equivalence, he should have just invented TurboTax.
