Lads, we're so stupid. We've been doing it wrong for years.
The quickest way to peel potatoes is not by hand, or with any sort of fancy peeler from an infomercial on late night TV, but this way. How have we been so blind? Think of the time we've wasted peeling potatoes when we could have been enjoying life. For shame world. Now excuse us while we go out and mechanise a toilet brush (a new one obviously). Just make sure it's clearly labeled 'Potato Brush', otherwise you're in for a very nasty time/infection.
