I've found that selecting a large baker type potato, for "sock use", makes an excellent dog deterrent, or for conking someone that needs an attitude adjustment. You can either bake the evidence and eat it, or, if feeling charitable, give it away to someone who will gladly dispose of the evidence for you.
I wielded one many times when I had two paper routes as a young boy, even smacked a hippie once who tried to jack my bicycle. I hit him so hard with a giant Baker that it knocked him down. Not too bad for a 12 year old....

The thing I like to ask the people who are so enthralled with this tech....So this technology is so very useful, powerful, and can basically run your life for you, it was designed and developed is maintained, expanded and improved constantly....but...the "service" is free and only requires a purchase of under $50 or is simply part of the free phone your cellphone provider handed you. Who paid for this and continues to? How does something like this become a billion dollar industry by charging nothing?
