The 'I Know Where You Live' Garfield meme stems from the internet obsession with 'cursed' or 'surreal' versions of Jim Davis's famous cat. While the phrase has appeared in various parodies, it gained significant traction through subcultures like 'I'm Sorry Jon' that transform the lasagna-loving feline into a menacing entity. The meme is typically used as a reaction to minor disagreements or to evoke a sense of ironic dread. Its popularity lies in the stark contrast between the cozy, domestic setting of the original comic strips and the overtly threatening tone of the caption, making it a staple for modern ironic humor.
