As Lisa writes her college application essay for Harvard, she recalls past disappointing birthdays that helped shape her.
- Artistic License Biology: Lisa claims rhinos are extinct at the time she's an adult, alluding to rhinos being endangered. In reality, the southern white rhinoceros, the south-western black rhinoceros, and the Indian rhinoceros would still be extant at her time, as they are not as rare as the other rhino species due to their populations thankfully increasing in recent years (although they are still threatened).
- Bait-and-Switch Comment: Back when Lisa became seven years old, her first-grade teacher told the class it's the birthday of someone whose parents pretended to have forgotten it. She was talking about one of Lisa's classmates.
- Continuity Nod:
- To Stark-Raving Dad: For Lisa's 14th birthday, Bart sings an updated version of the birthday song he sung back then and even brings the fake Michael Jackson who wrote it with him.
- To Flaming Moe's: When Flanders convinces Homer to quit drinking, Homer imagines a hell with Moe as the devil offering him a Flaming Moe.
- Imagine Spot: After giving up drinking, Homer imagines a Devil Moe trying to lure him back.
- Negative Continuity: In "Future Drama", Lisa goes to Yale instead of Harvard.
