Bests & Worsts Reviews from Amazon

My 8 year old son recieved these books as a Christmas gift. At the time I didn't think anything of it. Shortly after reading these he started giving his brother wedgies (which he had never heard of before) and he told me his teacher was idiotic because she told him he shouldn't talk in class. When I asked him where he learned this behavior from he said it was in the Captain Underpants books. I decided to read them. Admittedly, I should have done this prior to allowing him to read them. The two main characters are constantly doing inappropriate things. They are rude to their teacher and principal. In the one I read they said their science teacher was idiotic and his class was boring. They were making noises in class and when the teacher asked what was going on they told him he needed to see a doctor. They made up a brownie recipe that made the cafeteria explode. They wrote a comic about all the lunch ladies dying and turning into zombies. The list goes on and on, and this is only one book. I couldn't make myself read anymore. And if these things aren't bad enough, in just the first few pages there are so many intentionally misspelled words I was in shock. I want my son to read. I'm so happy he loves reading and I hate to discourage him from reading anything. However, these books are just totally inappropriate and defeat the whole purpose of him reading. My suggestion is to read them BEFORE you allow your child to.
