Captain Underpants/Funny

"Deputy Doo-Doo: Man, this hill is steep! I'm so tired! Danger Dog: Are you pooped? Deputy Doo-Doo: Why, yes, I'm... hey! Shut up! Danger Dog: Aw, don't be a party pooper! Deputy Doo-Doo: I said SHUT UP! Danger Dog: When we get home, will you read me "Winnie the Pooh?" Deputy Doo-Doo: I'LL KEEEEEL YOU!"
 * This exchange after Deputy Dangerous is turned into Deputy Doo-Doo:

"Harold: Where were you in chapter 15 when we needed you?! Captain Underpants: I was in the shoe store ordering a cheeseburger."
 * One of the warnings before a flip-o-rama suggests that if you find this chapter too disturbing, you should run to your nearest shoe store and order a cheeseburger. Later:


 * Another chapter ends with George and Harold saying they have to catch Mr. Krupp before he turns into Captain Underpants, but then the next chapter begins with said captain running down the hall crying jubilantly about underwear. The look on George and Harold's faces are PRICELESS.
