Pray, speak quietly, every sound you make is such exquisite agony to me.

Variously misattributed to Price's performances in the films Witchfinder General and House of Usher, but this line appears in neither of these films. The quote appears to have been based on a misremembering by Stephen Fry on an episode of QI. The actual lines Fry appears to have referenced are "If you'd please, Mr. Winthrop...softly. An affliction of the hearing. Sounds of any exaggerated degree cut into my brain like knives" and "Any sort of garment other than the softest, is agony to my flesh. My eyes are tormented by all but the faintest illumination. Odors assail me constantly, and as I've said, sounds of any degree whatsoever inspire me with terror."
