Something cracks me up

At the beginning when Lucy comes downstairs in the asylum, and takes the baby from its mother, there is the faint sound of bells. Swales, Dr. Seward's assistant portentously mutters sotto voce, "Sunken bells!" and Dr. Seward, surrounded by raving inmates responds contemptuously, "Sunken bells. Are you mad, Swales?" I look for this segment whenever I watch this movie, and it always makes me giggle; I don't know why.

I could be a morning person if morning happened at noon.
