Here we goin' to post some images of ragdolls in very awkward positions since PB2's ragdoll physics are pretty awesome. Also it ain't necessary for the character to be dead.
These include:
Flying so fast that the body parts get detached
Crushing into a ball
Hanging off a corner that it detaches head like with flying too fast but shorter
Characters holding guns with negative offsets
An example of those. (Here we have negative gun offset in correct position so it looks like it's marine's body, being detached is holding the head)
