[EX Q]: Can anyone who watches this movie ever erase from their mind the scene where Crawford finds out Palance and Grahame are plotting to kill her and goes stark, raving mad? It an Olympian display of overacting that has never been equalled: Crawford pulls at her hair, wildly darts her unfocused, bulging eyes, clamps her ears shut, pulls tight her grimacing mouth. A lunatic chimpanzee receiving electroshock couldn't do justice to Crawford's facial contortions here. I guess the reason that Crawford is such a fascinating screen presence to fans and nonfans alike is that she's a relentless masochist. In movie after movie, no matter what terrible fate befalls her, no matter how many times she is betrayed, it's nothing compared to the mental punishments she visits upon herself. The movie itself is serviceable but fairly ludicrous; there are glaring plot holes almost never seen in true film noir. The entire switched-identities ending is just about as bizarre as Crawford's performance.
[EX A]: Negative

[EX Q]: I just got this today and have been playing with it for a couple of hours and haven't gotten a decent orgasm. This is my first vibrator/toy ever and I don't think I will be buying any more. Maybe its just me but vibrations do little to nothing for me and the fact that this toys rabbit ears are way too long doesn't help. After playing with it for awhile and just being left frustrated I managed to get a weak orgasm not worth anywhere near the 30 dollars i paid for this! The vibe itself is way too thick and it has a awful chemical smell. I should saved my money! I will continue to try and play around with it but I am not hopeful. The rotating shaft also does NOTHING for me..
