I'd hazard to say that not many people could beat King's feat, though no doubt there are some fast catfish cleaners out there. This video tutorial claims to show how to clean catfish in 15 seconds. It takes the guy about double that, which is still pretty quick. Instead of skinning, he goes with a standard fillet job using an electric knife. It's a pretty good tutorial on how to clean a catfish that transfers to just about any species of fish. In fact, I use the same method with a sharp, non-electric blade for walleye and panfish.
