The 'I Don't Care Who the IRS Sends' meme originates from the animated series 'Dan Vs.', specifically the episode where the protagonist Dan refuses to pay his taxes. The scene features Dan shouting through his door at an IRS agent, and it has since become a popular exploitable template. Users typically swap the person at the door with someone intended to be persuasive or attractive, such as an anime character or a celebrity, only for Dan to remain steadfast in his refusal. It’s a staple of internet humor surrounding tax evasion and stubbornness, often used to mock various recruitment tactics or societal pressures.
