Making a 2D Ragdoll

Searched around and just could not find anything (maybe there is a sample around).
Anyway, wanted to make this easier I created an image for you all.

What I have been trying to learn and the Unity Free sample is just not very clear is how can you make a 2D character with the joints connected like a ragdoll?

Wanted to create some scripts for walking, running, etc, but stuck at locking each part together.

Any help or screen shots to show how would be great!
Example 2D human

You could use Hinge Joint 2D components to connect them.

Thank you I will give that a try.
