Every day you probably ask yourself an endless set of questions—What am I doing with my life? How do they get Wi-Fi on planes? Am I paying too much for car insurance? Why is my smartphone always dying at the worst possible moments? To answer the call of your most pressing queries and trickiest tech koans, the GEICO Gecko stepped in as an official WIRED Insider for the Green Guru series.

He helped clear up any confusion about the difference between analog and digital TV signals, which might’ve been clouding your brain. Gave a simple lowdown on how and why WiFi works on planes (the answer might surprise you) and even explained why rechargeable batteries weaken over time. He also put an end to the debate on whether or not the volume goes up during commercials.
