(Grandpa explains the story of Herb's conception to Homer.) Grandpa: It all happened when I was courting your mother. (Flash back to a younger Grandpa at a carnival.) Grandpa: (Narrating) I was checking out the skirts at the local carnival when I first saw her. Woman: (To Grandpa) Hey, handsome, wanna dunk the clown? Grandpa: (Narrating) She did things your mother would never do, like have sex for money. A year later, the carnival came back to town, and she had a little surprise for me. (The woman shows Grandpa baby Herb.) (Flash forward to present day.) Grandpa: We left the baby at the Shelbyville Orphanage, and I never saw him again. (Flash back to Grandpa at his wedding) Grandpa: (Narrating) A year later, I married your mother, and we had you. (Flash forward to Homer's mother after the delivery.) Mother Simpson: Abe, I want Homer to grow up respecting his father. He must never know about that-that carnival incident. Grandpa: Okay. Mother Simpson: Promise you won't tell him. Grandpa: I promise. (Flash forward to present day.) Grandpa: Whoops! Forget what I just told you.
Marge: Now we can blame him for everything! Homer: It's your fault I'm bald. Abe: It's your fault I'm old. Maggie: It's your fault I can't talk! Uncle Sam: It's your fault America has lost its way! Everyone: It's all your fault! It's all your fault! It's all your fault!
