Peter Griffin is the bumbling father at the centre of Family Guy, the long-running American animated sitcom created by Seth MacFarlane that first aired in 1999. Voiced by MacFarlane himself, Peter is known for his loud laugh, impulsive schemes and childlike optimism, which is why a happy clip of him travels so well outside the show. Shared through soundboards and short-form video edits, it has become a shorthand for cheerful celebration, letting creators borrow a familiar cartoon voice to mark a punchline, a victory or an unexpectedly wholesome moment.
