The line comes from Monty Python's Flying Circus, the BBC sketch show that first aired the Spanish Inquisition sketch in 1970. Led by Michael Palin as Cardinal Ximénez, the red robed inquisitors burst in whenever someone says they did not expect them, then resort to soft cushions and the comfy chair instead of real torture. The sketch became one of the troupe's most quoted routines, repeated in live shows and online clips, and its fake serious punishments still give creators a ready made joke for minor offences.
