The 'Pennywise in the Sewer' meme is derived from the iconic opening scene of the 2017 supernatural horror film IT, based on Stephen King's novel. The image captures the terrifying Pennywise the Dancing Clown peering out from a storm drain as he attempts to lure Georgie Denbrough closer. In the world of memes, this template is used to represent a person being tempted by something they desire, often despite the obvious danger or suspicious nature of the offer. Users typically label Pennywise with a tempting promise—like 'financial stability' or 'free pizza'—to highlight how easily people can be led into traps by their own desires.
