The 'It's Always Sunny in Philadelphia Title Card' meme mimics the show’s signature opening sequence, where a character's overconfident statement is immediately undercut by a title card displaying a contradicting or disastrous episode name. This comedic technique, known as 'The Gang Gets Undercut,' usually features white serif font on a stark black background, often including a timestamp like '10:30 AM on a Tuesday.' The meme took off as a way to mock real-world ironies, political gaffes, or personal failures where someone's hubris leads directly to a foreseeable catastrophe. It is widely used across social media to highlight the inevitable failure of a bad idea, capturing the show's dark, cynical humor perfectly.
