Einstein's Smoke Detector Lesson

Alright, listen up, you big dummy! You see Albert Einstein, right? The super-smart guy who came up with E=mc². Well, in this picture, he's not teaching fancy physics or relativity. Nope! He's showing a bunch of students how to put a 9-volt battery into a smoke detector, complete with a 'Chirp!!' for when it's low. The funny part is that a genius like him is explaining something so incredibly basic. It's like a Michelin star chef showing you how to make toast. It's unexpected, you know? You probably still don't change your smoke detector battery, do you?
