The line comes from the 1995 comedy film Tommy Boy, in which Chris Farley plays Tommy Callahan, a good-hearted but clumsy salesman trying to save his late father's auto-parts business. In one memorable scene he tries on a coat that is far too small for him, sings about it, and rips it apart. Shared for years as a short reaction clip on soundboards and social media, it endures because the visual gag needs almost no context: everyone understands trying to squeeze into something that was never going to fit.
