Because Ms. Briggs is mean to everyone, Carly and Freddie spy on Ms. Briggs to see what mean teachers do after school for a segment on iCarly. They find out she is addicted to Randy Jackson and they eventually get caught when Sam tries to get them out. She threatens to call the police and expel them unless she performs on her webshow. She ends up performing on the bagpipes and their view count drops instantly. But when they use the green screen to get hilarious backgrounds, people come back and iCarly has more viewers than ever. Meanwhile, Spencer has a girlfriend who can juggle. Note: Final appearence of Miss Briggs.
