First off, I'm sorry if this thread is a bit out of left field/ in the category of "okay, who cares?," but I was surprised to find it out and wanted to know if anyone else had tried/discovered this.
Chewbacca's neck articulation has traditionally been in most figures, well, not really all that articulated. In every Chewie since the Vintage Chewies he's had a seperately molded head, but the hair usually keeps it from being adjustable at all, except in a few cases such as one Saga Chewbacca that had a hinged neck joint.
So, I was removing the paint from my effort-gone-awry to customize/improve the paintjob of my MFM Chewie, only to discover that with a little careful pushing,
his head turned to the side. I'm pretty sure this hasn't damaged the head or neck joint at all; and he doesn't need to be warmed to do it. The hair that hangs down on his shoulders is pretty soft, and with a little effort his head is indeed simply a working articulation point. This doesn't work on POTF2 Chewbacca- I've tried numerous times with him before, I think his head might be actually made of styrene (the hard plastic used for torsos until the last couple years).
A little bit needs to go a long way when a figure has simple articulation, and this neck articulation makes Chewie's right arm a lot more useful for shooting poses and such. I'm pretty happy it's there now that I realize it can be used.
As proof, I offer this horrid-quality scanned picture:

So, has anyone else done this? Do newer Chewbaccas, like VOTC Chewie maybe, also do this?
