Step Brothers is a 2008 comedy starring Will Ferrell as Brennan Huff and John C. Reilly as Dale Doback, two middle-aged men who become stepbrothers when their parents marry. Their friendship begins when they discover how much they have in common, despite starting out as rivals for space in the family home. The scene became one of the film's most quoted moments and spread through clips, reaction videos and memes about instant friendship. It still works because the sudden bond is both absurd and relatable, making it an easy shorthand for any new duo.
