The Futurama Fry meme, also known as 'Not Sure If,' features the character Philip J. Fry squinting his eyes in suspicion. The image originates from the season two episode 'Lesser of Two Evils,' where Fry mimics another character's facial expression. It first gained viral traction on Reddit and Tumblr around 2011, quickly evolving into a staple template for expressing internal monologues and ambiguity. Usually formatted with the phrase 'Not sure if [option A] or just [option B],' it remains one of the most enduring symbols of internet skepticism and confusion.
