If you're a dad your slippers are a very important part of your wardrobe. Firstly: They should be comfortable for everyday wear around the house. Secondly: They need to have a hard sole that will sting a naughty boy's bottom when needed. Since slippers are an integral part of dad's wardrobe, they are always close to hand and therefore, close to a boy's bottom. It is simple for dad to slip his slipper off his foot an apply it to a deserving bottom right on the spot. Having received the slipper on numerous occasions, I can attest to its usefulness!
