Jennette McCurdy & Jane Lynch: Pile of Pucketts!

Jennette McCurdy gets pinned down by special guest star Jane Lynch in this brand-new still from iCarly.

In the upcoming episode “iSam’s Mom,” Sam (McCurdy) moves into Carly (Miranda Cosgrove) and Spencer’s (Jerry Trainor) apartment after having an argument with her mother Pam (Lynch). Sam’s peculiar habits make her a terrible house guest and she quickly wears on Spencer and Carly’s patience.

Desperate to have her move out, Carly tricks Sam and Pam into meeting at a therapist’s office so they can reconcile their differences. Carly unwittingly gets stuck with the fiery twosome when they are put in a “Therapy Box,” a small confined space where they must talk through their issues before they can be let out.

“iSam’s Mom” premieres NEXT Saturday, September 11 @ 8PM ET/PT on Nickelodeon. 10+ stills inside…
