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.
