Teacher: Okay, it's time to take a test on Rugrats in Paris.
Derek: Oh no! I forgot to study!
Teacher: Good luck.
Derek: I will cheat off of Emily's test.
Emily: Hey! You cheated off my test!
Teacher: What's wrong Emily?
Emily: Derek cheated on my test!
Teacher (Kidaroo's voice); OH OH OH OH OH OH OH OH OH OH OH OH! DEREK, HOW DARE YOU CHEAT OFF OF EMILY'S TEST! THAT'S IT! GO TO THE PRINCIPAL'S OFFICE AND I AM TAKING YOUR TEST!
Dylan: Why is my girlfriend mad at Derek?
Teacher: Because he cheated off her test.
Dylan: I know. We hate it when people cheat off of other's tests because it makes them mad.
Principal: So Derek, why are you here?
Derek: I cheated off of Emily's test.
Principal (Scary Voice): WHY? WHY? WHY? WHY? WHY? WHY? WHY? WHY? WHY? WHY? HOW COULD YOU? THAT'S IT! GO HOME NOW!
Derek's dad: Derek, how dare you cheat on your test in school! That's it! You are grounded forever and as for your punishment, I'm taking you to the hospital to get your voice changed.
Keith: Please, Rachel. I don't want my voice changed. I only liked how you were before.
Rachel: Too bad Keith! If you hadn't changed my voice to Princess, we wouldn't have been in this situation! Also, your dad caught me having Princess as my voice so he grounded me as well and changed it back to Steven!
Doctor: The doctor is here.
Derek's dad: Change my son's voice because he cheated off of his test.
Doctor: Let's test it out.
Derek (speaking in Kimberly's voice): Oh no! My voice is Kimberly! Now I sound like my sister Kumi!
Doctor: How's this?
Derek's dad: It's perfect. Let's go home now.
Derek's voice will stay as Kumi.
