During this episode, Abed, played by Danny Pudi, speaks Polish with his Polish floormate. In real life, Pudi is half Polish and speaks it fluently.
When Pavel comes into Abed's dorm room, Abed says, in Polish, "Czesc kolega, to jest Britta," which translates to "Hi buddy, this is Britta". Later on in the scene, Abed says "siadaj" which means "sit down". Later on in the episode, Jeff says he is heading back because Pavel's making "babka," which is a traditional Slavic sweet yeast cake, usually served during Easter.
Britta says that slovenly, college-bum Jeff has "a real Phil Spector vibe going". Spector was one of the most influential producers in 1970s rock and roll. In 2009 during his second trial on charges of murdering actress Lana Clarkson, Spector looked truely unhinged and demented, and was generally perceived as a habitual and dangerous abuser of women.
Jeff (Joel McHale) attempts to make money by apparently selling Spider-Man comic books; McHale appeared in Spider-Man 2 (2004).
The movie posters in Abed's room are Back to the Future, Back to the Future 2, Short Circuit 2, Batteries Not Included, Stand by Me, It Came from Beneath the Sea, and Vibes.
