Mac is sitting and reading a science book. Bloo comes in.
Bloo: Hey, Mac.
Mac: Hi, Bloo.
Bloo: What's up?
Mac: Nothing. Just studying for the Big Science Test.
Bloo: Studying?! Why study when you should be PLAYING?!
Mac: My mom says that if I don't pass, I can never come back to Foster's ever again! Never!
Bloo: Never come back to Foster's again?! Never?! OK! Let's get studyin'! So… What are we studying? Math?
Mac: Uh… It's the Big SCIENCE Test, Bloo! I already passed the Big Math Test!
Bloo: Oh. (Sarcastically) Right. (Back to normal) What's this book for?
He holds up Mac's textbook.
Mac: It's my science book.
Bloo: Why use a book when you can ACTIVELY study?!
He throws the book away.
