Episode 128 of "Sabrina, the teenage witch"
s06e09 A Birthday Witch

Sabrina wants to spend her birthday with her boyfriend, Josh, but her Aunt Irma (Barbara Eden) comes to visit from the Other Realm and puts Harvey on trial because he knows Sabrina is a witch and is determined to test him to see where his loyalties lie. Meanwhile, Roxie's (Soleil Moon Frye) ex-boyfriend Isaac Hanson, playing himself, surprises her by performing with his brothers Taylor and Zac, at the soup kitchen where she volunteers. Sabrina, excited about her upcoming birthday bash, asks the aunts if she can invite Josh to the family celebration. It sounds like a great plan until Hilda and Zelda get a call from Aunt Irma (guest star Barbara Eden, "I Dream of Jeannie"), matriarch of the Spellman clan. She's discovered that Harvey knows the Spellman secret and insists on visiting to interrogate the mortal to see if he can be trusted to keep quiet about the witch thing. Poor Harvey. Sabrina has to tell Josh that he can't attend her birthday dinner because it's just a family thing and beg Harvey to come over and defend himself.Fearing the wrath of Aunt Irma, Hilda and Zelda do everything they can to make sure she's happy. But, when Aunt Irma arrives they all tremble under her steely gaze. Harvey endures every form of torture that Aunt Irma can think of before she asks him one last question — is she an attractive woman? Harvey answers honestly: on the outside she is, but on the inside she's ugly and mean. Accepting his answer as the truth, Aunt Irma relents and is willing to believe that Harvey will keep the secret. Unfortunately, Josh has come by to drop off Sabrina's birthday present and spies Sabrina and Harvey hugging. Thinking the worst, he heads to the soup kitchen to join Roxy. Roxy is busy making a dinner menu because her friend Isaac is coming for a visit. She then 'fesses up that he's not just a friend and he's not just an ordinary guy. Her ex-boyfriend is none other than Isaac Hanson (guest-starring as himself), from the rock group Hanson. Roxy's not the only one disappointed when Isaac calls to say he can't make it after all. Roxy and Miles head down to the soup kitchen to put the special dinner to good use. Isaac stops by the house trying to catch Roxy and finds super-fan Morgan instead. They head over to the soup kitchen to find Roxy. When Sabrina stops by the house she finds Hilda, Zelda and Salem transformed into pigs. Summoning Aunt Irma from the Other Realm, Sabrina begs her to undo the spell. When Aunt Irma refuses, Sabrina stands up to her, telling her exactly how she feels about Aunt Irma's treatment of people. Instead of becoming a pig herself, Sabrina is surprised when Aunt Irma admires her for standing her ground, saying that kind of spunk will land her as the Spellman matriarch someday. Sabrina calls Josh and discovers that he's mad at her and suspects her of having a secret relationship with Harvey. She assures him that he's the only one for her and takes him back to the Spellman house for her birthday dinner. Afterwards, they head down to the soup kitchen as well, where Isaac and his brothers Taylor and Zac perform a song for Roxy.
