Rachel Chappell writes the following about Captain Underpants :
I am a girl and I still love all of the Captain Underpants books! They are just so funny and interesting, you can not help but to fall in-love with them! My favorite would have to be the first one. You will laugh and laugh till you cry. I have never read anything like the Captain Underpants books. So you should really read one they are amazing! I didn't think I like it but I love them!
