The line comes from Doctor Who's 60th anniversary specials in 2023, where the returning Celestial Toymaker confronts the Doctor and taunts him over companions he has lost along the way. Neil Patrick Harris plays the Toymaker in that return, bringing a theatrical, teasing menace to the role. Clipped from that confrontation, the exchange has circulated among Doctor Who fans as a reaction sound for moments of dark acceptance, because the character's cheerful dismissal makes a painful history sound almost trivial. Its appeal lies in that contrast, which works even for viewers who only recognise the tone, not the story.
