The Fibonacci number (or sequence, or series) is the mathematical rule that defines the golden spiral, a beautiful growing pattern that appears in many places in nature. It also appears on YouTube when you search "Fibonacci," and it's just silly enough to make us smile.

Watch closely; when you search Fibonacci, the results show up in a golden spiral that follows the Fibonacci sequence. We're not sure how long this little easter egg has been around, but it's perfect. Clearly, the nerds at YouTube are having fun, in a way that makes the nerds here at Gizmodo feel warm nerd feelings. [H/T @vladsavov]
