iWanna Stay! (iCarly)

Carly and Sam decide that their next iCarly Webcast should be all about what teachers do outside of school. And who better to be the subject of their Webcast than Ms. Briggs? But when Carly and Freddie end up trapped in Ms. Briggs's closet, it's up to Sam to save them!
When Carly's grandfather arrives for a visit, he doesn't like what he
sees. He thinks Spencer is too immature to be Carly's guardian and
wants her to come and live with him. Is it bye-bye Sam, Freddie,
and iCarly?
