Bonus Ducks originated from the multiplayer shooter Team Fortress 2 during the 2014 End of the Line update. When the character Merasmus the Magician appears, he frequently shouts the catchphrase 'BONUS DUCKS!' as rubber ducks spawn across the map. The line, delivered with eccentric enthusiasm by voice actor Nolan North, quickly became a viral sensation within the gaming community due to its absurdity and sudden volume. It is typically used to represent unexpected windfalls, chaotic events, or simply as a nostalgic nod to TF2’s quirky sense of humor. Today, the meme survives as a symbol of the game's enduring legacy and the community's love for its bizarre characters.
