How to escape from a strait jacket

1. While you're being buckled up, use one of your hands to inconspicuously pinch the front, giving you about three inches of slack. Take a deep breath and tighten your muscles in order to make your upper body as big as you possibly can. As your sleeves are pulled behind you, try to make sure your stronger arm is over your weaker arm.
2. Loosen up. Once the straitjacket is secured, relax your upper body and breathe out. Make your upper body as small as possible, and let go of the slack you created in the previous step. The straitjacket should feel looser now.
3. Push your strong arm forcefully towards the opposite shoulder. This will move the slack to where you need it for the next step.
4. Bring your strong arm up and over your head. Keep your weak arm down. Once you've done this, you'll be able to move your arms around.
5. Unbuckle the sleeve buckle with your teeth.
6. Unbuckle the top and bottom buckles behind you, using your free hands.
7. Step on the material of one of your sleeves while tugging your body out of the straitjacket.

I wonder how many tries it would take to actually pull this off (no pun intended, as far as you're concerned). Alas, I'm not willing to give it a go.

BFallen: Since when does being put into a straight jacket have anything to do with being willing?
