This is definitely one of the weirder questions I've asked, but is there any easy way to massage an octopus? I recently watched the movie "Jiro Dreams of Sushi" and in that movie they show the massaging of the octopus which Jiro insists must be done for 50 minutes. There is no way I am going to spend an hour massaging an octopus. In the video here we can see a different master sushi chef demonstrating massaging octopus: https://www.youtube.com/watch?v=89wwP--bHMg According to this guy his father massaged the octopus by putting it in a washing machine. I am not sure I want to try that and am wondering if there is a kitchen oriented way to massage an octopus rather than using the laundry room? 
In the olden days fishermen used to "beat" or hit the octopus against a rock on the shore repeatedly. The main purpose of this endeavour was to soften its hard texture, so that it would take less time to cook it. The other (and more modern) option is to put a fresh octopus in a freezer and let it deep freeze for at least several hours. That breaks down "the fibers or texture"  of the meat.
