Animating Stick Figures (Puppet tool?)

Hello, I have a client who, in the next few weeks/days will be requesting that we produce a commercial spot using road-sign stick figures to walk across the screen. Obviously, there's a million ways to do this, but what is the quickest and most effective way of doing this? Should I cut out each limb in photoshop, and just parent them together, or is the puppet tool the way to go? I gave a quick test with the puppet tool a few weeks ago, and it seems to kinda bend and distort things in a fairly unnatural way, especially if you're wanting straight lines. And making a character walk with the puppet tool seems to not go so well, but if anyone has any suggestions, that would be helpful.
