So there's this mathematical phenomenon that appears throughout theory, application, and numbers, derived from what was discovered as a function called the Fibonacci Sequence. It's related to the Golden Ratio in mathematics.
See, Wednesday is Fibonacci Day in America, because the numerical series is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 and so on, following the formula forever. Wednesday is 5/8/13. So today in America is celebrated as Fibonacci Day.
And the Bulls' starting lineup, as pointed out by a delightful Reddit thread, is
No.2 Nate Robinson
No. 5 Carlos Boozer
No. 8 Marco Belinelli
No. 13 Joakim Noah

This is like The Da Vinci Code, only with Nate Robinson instead.
