Homer, Moe, Lenny, and Carl share a winning lottery ticket, but when Carl makes off with the winnings, the others follow him to his country of origin, Iceland, where they learn why Carl would abscond with their lottery winnings.
- Anime Land: Bart and Lisa watch a show, "Ki-Ya Karate Monsters", that is clearly intended as a parody of the genre.
- Beware the Nice Ones: Lenny takes Carl's betrayal very hard and attacks him. Immediately Lampshaded by Moe.
Moe: When the nice ones snap, it's always a good show.
- Clear Their Name: Carl uses the money to clear the dishonour of his family name by buying the missing page of the saga that depicts them as cowards who abandoned their post Only to find that his ancestors were actually worse than what the saga depicts.
- Does This Remind You of Anything?: Homer watches female tennis and describes it as "soft-core tennis".
- Getting Crap Past the Radar: Homer doesn't know why people laugh upon the mention of the number 69 (and for those who don't get it at home, "69" is a sex position where both partners give each other oral sex).
- Hyper Focused Crowd: While staking out Carl's family home, the guys get bored and decide to pass the time reading the manual for their rental car, oblivious to not only the northern lights behind them, but also the dancing trolls and fairies surrounding them.
- Implausible Deniability: Homer and Lenny deny Carl's betrayal for a very long time, despite all signs to the contrary.
- In the Blood: Betraying friends is in Carl's adopted blood.
- National Stereotypes:
- Truth in Television Iceland is portrayed as a country with a small population, though caricatured here to the point that all inhabitants can apparently crowd together in one spot instantly without anyone missing.
- References are made to geysers, Icelandic sagas, Björk, Viking invasions, the Allied Forces occupation during World War II for strategic reasons, the Northern Lights, fairies, elves, trolls, Sigur Rós, the 2008-2011 economical collapse and their former lesbian Prime Minister Jóhanna Sigurđardóttir (who was, in fact, the very first openly lesbian head of government in the world).
- Special Guest: Sigur Rós plays the closing theme.
- Suspect Is Hatless: When the guys ask around for Carl in Iceland.
Moe: Say, have you seen our friend? He's about this tall, wears a jacket, has no visible tattoos...
Homer: Just say he's black.
Moe: You say he's black!
