There have been several times that I have had to make a huge potato salad or a lot of mashed potatoes in a short amount of time. I usually have to use an entire bag of potatoes (I have a big family). I am pretty good at doing everything except peeling the potatoes. Is there any way to quickly peel an entire bag of potatoes?
The Super Peeler
Warning: only do this outside
This method takes some time to prepare, but you only have to prepare it once and every other time you do it, it will be ready.
You need a bucket, a hose, a drill, and a new toilet bowl brush. Drill a hole in the bottom of the brush's handle and keep the drill there. Spin the brush a few times to make sure it sticks. Fill the bucket with the potatoes. Now put the brush attached to the drill in the bucket, between the potatoes. Start filling the bucket with water, while you spin the brush using the drill. In about 60 seconds, all of the potatoes will be peeled.

If you boil the potatoes first, you can peel them by simply rubbing the skin off of them. (And you are not likely to require medical attention with this technique!)
It's explained nicely at this link from Creek Line House. They say it takes about two seconds per potato. I've used this method myself. It works. If you can handle the hot potatoes (use a rag or some glove to handle them), you can skip the ice step.
