Exclusive: Watch Jane Lynch Make Her Comedic iCarly Debut

Jane Lynch is trading her megaphone for mom jeans in her iCarly debut on the upcoming episode "iSam's Mom," on Nickelodeon.

Jane Lynch to be a mom — on iCarly

The Glee Emmy winner plays Pam, cranky mom to Sam (Jennette McCurdy). In this exclusive sneak peek, Carly (Miranda Cosgrove) convinces the bickering pair to see a therapist to work out their differences. And that's where the trouble starts.

"You married? I don't see a ring. You got a woman or what?" Pam asks the therapist. "Pardon my mommy's desperation," Sam sarcastically responds.

The Sept. 11 episode (8/7c) is the first appearance of Sam's sassy, eccentric mom, who has a colorful dating life, horrible driving skills, and questionable hygiene.
