Well, I wouldn't say I'm trying to do anything that clever. It's just an exaggerated form of collectivism.

Nah, that'd be giving myself too much credit. But one of the reasons I had Freakboy get covered in ketchup is to make it a little easier for readers to tell him apart from his roommate. He won't be ketchup'd in the following chapters, so it might end up getting a little confusing trying to follow their dialogue. The only difference between them visually is their body language and Freakboy's letter.
