The 'Tony Soprano In This House' meme comes from the acclaimed HBO series The Sopranos, specifically the Season 4 episode 'Whoever Did This.' In a heated moment with his family, Tony asserts his authority by shouting, 'In this house, Christopher Columbus is a hero! End of story!' The meme format is used to humorously declare a non-negotiable stance or a 'house rule' about pop culture, sports, or personal opinions. By swapping out the subject of Tony's declaration, creators use his intense energy to defend their own favorite (and often controversial) hills to die on.
