The 'Newsflash Asshole' meme originates from the Season 11 episode of 'It's Always Sunny in Philadelphia' titled 'Mac and Dennis Move to the Suburbs.' In the scene, a sleep-deprived and mentally breaking Dennis Reynolds screams at Mac about a chirping smoke detector, delivering the iconic line: 'Newsflash, asshole! I've been hearing it the entire goddamn time!' This template became a staple for internet users wanting to express intense frustration or sarcasm toward someone stating the obvious. It perfectly captures the feeling of being pushed to the brink by unsolicited advice or redundant information, making it one of the most popular reaction images featuring Glenn Howerton’s legendary character acting.
