The audio comes from Garth Marenghi's Darkplace, the Channel 4 horror-comedy that aired in 2004, where Matt Berry played Dr Lucien Sanchez alongside Matthew Holness and Alice Lowe. The series became a cult favourite for its deliberately bad acting and overwrought dialogue. Clips of Berry's Sanchez, with his deep voice and womanising swagger, circulate widely among British comedy fans. This oath moment is shared as a soundboard favourite because it condenses his pompous doctor persona into a single ironic line, useful for mock-serious medical jokes online.
