Quote from Michael Scott in Double Date
Pam: Mom, have you decided what you want to be called? Helene: Oh, well I like Nana, but I also like the classic Grandma. Pam: Please be Grandma. Jim: Definitely Grandma. Pam: I want you to be Grandma. Helene: Oh, Michael what do you think? Grandma? Michael Scott: [nods uncomfortably] That. Pam: Yay, Grandma!
