Well basically, you just ask people if they remember something about iCarly. You can do Seddie and Creddie quizzes too but please no fighting. Here's some easy examples:
iCarly: Who made up the name iCarly and what episode did they start doing it??
Seddie: How long was the first kiss??
Creddie: What episode did Carly and Freddie dance??
Now what quizzes do you have in store for people?? How do I know if you don't comment?? :D
