Skeptical Baby, featuring a young boy named Mason giving a sharp, judgmental side-eye, first rose to fame in late 2011 after being posted on Reddit. The image perfectly captures the essence of disbelief and suspicion, making it the go-to template for questioning absurd situations or everyday white lies told to children. Often paired with the phrase 'You mean to tell me...', the meme satirizes the moment a child realizes the world isn't quite what adults have led them to believe. Its enduring popularity stems from its relatable expression, which remains a staple in reaction image culture for highlighting skepticism in any context.
