The line comes from The A-Team, the NBC action series that ran from 1983 to 1987. It was the signature catchphrase of Colonel John Hannibal Smith, played by George Peppard, usually delivered while he smoked a cigar after the team's elaborate scheme succeeded. The show's reruns and 2010 film kept the quote alive, and it became a staple reaction clip on soundboards and meme pages. Creators still use it because it instantly frames any successful outcome as clever and intentional.
