The line comes from Piemations' 5 AM at Freddy's: The Prequel, part of the animator's long-running animated parody of the horror game Five Nights at Freddy's. Piemations built a large YouTube following with musical FNAF spoofs that reimagine Freddy Fazbear and the animatronic cast in absurd comic situations. Short quotable moments like this one get clipped by fans and uploaded to meme soundboards, where FNAF fans reuse them as reaction audio. The 'two Freddys' gag endures because mistaken-identity and seeing-double jokes never go out of style in meme edits.
