Howard reveals that although he has numerous belt buckles he only owns one belt.
As in The Weekend Vortex, which aired two episodes previously, we hear the shrill voice of Mrs. Wolowitz at a location besides her house.
This episode is mostly the guys. Mayim Bialik is absent and Kaley Cuoco and Melissa Rauch each appear in only one scene.
The title refers to Sheldon's excitement at meeting his idol, Steven Hawking.
Howard: Why should I do something nice for you?
Sheldon: To go to Jewish heaven.
Howard: Jews don't have heaven.
Sheldon: To avoid Jewish hell?
Howard: Have you met my mother? I live in Jewish hell.
Bernadette: Sheldon doesn't know when he's being mean because the part of his brain that should know is getting a wedgie from the rest of his brain.
Mrs. Wolowitz: (from the change room in the department store) You're right. Who am I kidding? You should have seen me when I was young, Sheldon. The fellas used to line up and bring me boxes of candy. Why did I eat it all?
