Disgusting. Not worth your time.

Okay, but some changes can be made to make it more kid friendly and interesting.

Most people have pointed out how uneducational and trashy this series can be, and I fully agree. With villains like Professor Poopypants and Wedgie Woman, toilet humour is inevitable in these books. However, it wouldn't matter if it was a graphic novel about Richard Simmons on a quest to find a magical talking leotard of wisdom and prosperity... if it's a gateway book to reading, it's a good thing, regardless of how immature it can be. And yes, it is immature, but it got a lot of kids hooked on reading when it came out (what do you expect kids to read in elementary school? Pride and Prejudice?), and not only that, but it's got those random moments on occasions that are just wildly hilarious-- to me, at least.

it is a good book but gross,like where do you get the ideas of a 3-d hypno ring that turns your grumpy princable to a super hero that saves the world and battles dr. diaper. And that is also violence. and there is bad messages played by the role models which make them bad. Like them changing the ad that was on the board to something gross. But most small kids will think is pretty funny even i think it is kinda funny. but it is a good book for 6+.

Funny when you're six. Rubbish immature trash when you're over nine. This silly yet harmless adventure of a man running around in his underpants will entertain and amuse young kids.

Captain Underpants is very funny and is made so you can laugh and fall on the floor laughing! There is some nude where Principal Krupp changes into Capitain Underpants and very crazy parts too!

The kids do so much damage. Captain Underpants saves them. The princapal doesn't even know it's him that's captain underpants! It's amazing how they defeat villians. I just think this book is good for young children out there. There I end it!

What the person on top said. Potty humor. I used to read him every night until they stopped coming out with new books. One time, I read it in the middle of the night and I burst out laughing. I wonder if anyone heard me...
