There must be nerve clusters in his butt that are directly connected to the learning center of his brain. He is almost completely unable to do his homework without this stimuli being applied. This is most applicable to math, which is odd as it is his best subject. Let me rephrase that, it is his best subject... when you can get him to do it. Math seems to come natural for him, and if he actually sits down and does it, he is able to do it quickly. It is just getting him to do it, which is where the spanking comes into play.
I'm reminded of the Bill Cosby routine about 20 years ago where his monologue sketches through one evening. He tells about getting his kids through dinner, and into the shower, specifying them to take off their clothes, turn on the water, get into the shower, wash themselves, rinse themselves, turn off the water, dry themselves, put on pajamas and get into bed. It cumulates in the revelation that the kids can't go to bed until they've "had their beatings".
Yep, that's homework for my kids in my house. #3 puts more time and effort into having an attitude about it and not doing it, that he would put in actually doing it.
OK, off to stimulate the mind of #3.
