Oh my, you've grown!
Barri's grandfather is, as his name implies, the grandfather of Barri, an unseen girl who had a Bat Mitzvah. He makes his sole appearance in "Bat Mitzvah Crashers."
His voice is provided by Dee Bradley Baker.
He first appears and asks Penny (thinking she is Barri) for a dance. When Penny jumps into his arms, he remarks "Oh my, you've grown!"
Later, at Chelsea's Bat Mitzvah, Bessie, Penny and Portia meet him in the dining room. Barri's grandfather calls for Penny, and she asks if they can all hide under the table. He obliges their request.
Allowing Chelsea to catch up to the girls, she believes to have finally caught them, but Portia and company manage to escape by the time Chelsea realizes what's happened.
Barri's grandfather is a light-skinned elderly man who is balding, only having dark gray hair on the back of his head in addition to a handlebar mustache of the same color. He wears black glasses, a dark blue tie, white undershirt, a brown jacket, pants that are a lighter shade of brown, white socks and black shoes.
- In the closing credits, he is listed as "Elderly Man."
- As his granddaughter had a Bat Mitzvah, this means he is Jewish.
- His nicknames for Barri are "sweetie" and "kiddo," while she calls her grandfather "Grandpa."
- Baker reuses the voice for Barri's grandfather as a senior citizen at a retirement home in "Toot Toot." However, as he did not appear onscreen, it is unknown if this is meant to be the same character.
