Bart: Hey, Homer, how come Mom's going to the doctor?
Lisa: Is anything wrong?
Homer: No, everything's fine. Your mother uh just... broke her leg.
Bart: I smell a bun in the oven...
Lisa: Is Mom going to have another baby, Dad?
Homer: [fierce internal struggle manifests itself in wiggling fingers]
Bart+Lisa: Whoa, awright! Way to go! [exchange high fives]
Bart: You're a machine, Homer!
