The 'Why shouldn't I keep it?' meme is taken from the 2001 fantasy epic The Lord of the Rings: The Fellowship of the Ring. In the scene, Bilbo Baggins is about to leave the Shire but finds himself unable to part with the One Ring, muttering the iconic line to himself. The internet quickly turned this moment of intense temptation into a relatable meme for any situation where someone wants to keep something they probably shouldn't—like an extra slice of cake, fifty open browser tabs, or a bad habit. It remains a staple format for expressing greed and lighthearted obsession.
