You may remember a flick from the 80s called "Mannequin"... it starred Brat Packer Andrew McCarthy and Kim Cattrall (very Pre-SATC). The basic premise was that a guy was in love with this "magical" mannequin who would randomly come to life. (Of course, only around him!) Misunderstandings and bad puns ensued.
Fast forward two decades, now there is a man named Ronald Dotson in Michigan who may be suffering from the same problem. According to the AP the guy was arrested "after breaking a window at a cleaning-supply company to get at a mannequin in a black and white French maid’s uniform." Hey un-pop-cultured police! That is probably his girlfriend!
Apparently he has been stealing mannequins for over thirteen years (or six years after the release of the movie). I think the best defense would be to show clips of the movie. The jury would probably think it was a documentary and take pity on him. After all, if "Pretty in Pink" star Andrew McCarthy did it too, it can't really be that bad!
