Its Not Such A Wonderful Life : Mr. Potter Strikes Back

George Bailey, wife Donna Reed and kids, sleeping soundly with bellies full of good clean protestant eggnog, do not hear the furtive squeakings of a wheeled chair slowly lurching upon their happy brown-hued bungalow-type residence, amidst the intentionally disquieting sound of a cello playing first a low note, then going up 1/2 step and playing that, then back down and playing the first note again, now repeating the sequence over and over and over, growing slowing but perceptibly faster and louder -

now, from inside thru the curtains, we begin to see the approach of a darkly cloaked yet white & fat seated human figure. a match is struck, it flares as only a good old wooden match can, & is set to something dangling from what appears to be some manner of bottle -

cut to a profile of a quietly but demonically cackling John Barrymore - all on a sudden the cello is joined with a quite loud & discordant & intentionally unpleasant sequence of violin screeches, as snarling & sneering & leering, the aforementioned Barrymore, playing the part of Mr. Potter, makes the volte-face into the eye of the camera -

he now, as the voilin begins a dramatic, lusty descent of an octave down to a minor third, with a shriek of his own providing an even additional note of unpleasant discordance to the cello and violins, thereupon chucks, with surprisingly energetic & masculine vigor especially for such a crippled old geezer, the incendiary object thru the lovely beveled window into the nicely appointed front parlor, catching the tasteful yet flammable irish lace curtains on fire - within but seconds the whole lovely room starts to go up in flames! and then...

ah well, i'm boring you.

so..... what's yours?
