My vote goes to "Satan's Right Hand". Maybe you should add the choice of "Satan's Anal Polyps" or "Satan's Perforated Rectum". "Lucifer's Anal Leakage"?
Like I said about my one particular ex, there are some ex's out there(male and female) who are just too plain evil for even Satan to handle. Mine was a blend of J'inn's shoposaurus rex and Glenn Close in "Fatal Attraction". She'd drag me halfway across the state on shopping sprees(blowing $500 on a couple of pairs of jeans was nothing to her), call me up at three in the morning, totally drunk, and keep me up till she fell asleep on the phone. This wasn't a once in a relationship moment, it was the norm.
This went on for over six months until one beautiful Sunday afternoon in '95?(I forget), when I turned the tables on her by accident and she shed her costume to reveal the truly heinous bitch she was. My sister and I had a friend from high school who was dating a guy who was, shall we say, "connected"(The DoJ would occasionally freeze his assets, but he never talked, at least to my knowledge). Anyway, they'd invited us over to watch the Niners-Cowboys game and enjoy some steaks from the grill and surprise!, there was plenty of great wine on hand.
After the four of us consumed some great T-bones, the game, and lots of wine, my sister dropped me off at my place around 7 that evening. At this point, I realized I was in no shape to go out that evening(we were supposed to go see a movie) and my roommate informed me she had called about 5 times in the previous hour. I called her and told her I was too tired and sleepy to go out and then, Glenn Close came on the phone, screaming, yelling, cursing, howling at the moon, and bitching me out for standing her up(apparently, in her 26 year life, no man had ever dared do that). After about a minute, the alcohol having a positive role, I hollered at her to shut up, then proceeded to chew her out nonstop for over 3 minutes. When I was done, I yelled "Goodnight!" and slammed the phone. My roommate applauded(by this point, he couldn't stand her either) and made me go to sleep. He proceeded to block her calls for two days until I was ready to stand her down. When she finally got through, she was apologetic, sad, and begging for another chance.
Being dumb enough, I gave her one last date, and we went to dinner. It became apparent before even the entree that she was doing this for ego. Not only had she never been stood up, but no man had ever broken up with her. We danced through this for a couple of months before I'd had enough and finally told her to get lost.
That's why I voted for Bal-rog, because Sauron or Succubus weren't on the list.
