The "Good Fellas Hilarious" meme originates from a pivotal scene in Martin Scorsese's 1990 crime drama *Goodfellas*. The image features actor Ray Liotta as Henry Hill, laughing intensely and and nervously, while Joe Pesci's character, Tommy DeVito, questions him with the iconic line, "You think I'm funny?" The meme captures a moment of exaggerated, often uncomfortable or forced laughter. It's typically used to represent situations where someone is laughing awkwardly, nervously, or simply pretending to find something funny to appease another person or diffuse tension. It can also ironically depict someone laughing at their own bad joke or an overly enthusiastic reaction to something mildly amusing. Its usage often highlights social awkwardness or a lack of genuine amusement, making it a versatile reaction image in various online contexts.
