Sentence:  If the distribution of decimal digits of π (or any other <WSD>transcendental</WSD> number) is truly random (suspected but not yet mathematically proven!), given any arbitrary finite sequence of whole numbers, that sequence would be included an infinite number of times in the decimal expansion of π. 
Meaning of the word marked with <WSD> tags:  Not algebraic (i.e., not the root of any polynomial that has positive degree and rational coefficients).
