Near the end of the episode Snot selects Cheetos from a vending machine, and picks number B7. In Can I Be Frank with You? (2012) when the boy band Boys12 is formed, he is B7.
Steve describes the girl he meets as a "manic pixie dream girl." This is a term coined by film critic Nathan Rabin. It was inspired by Kirsten Dunst in the film Elizabethtown (2005) and is defined as "that bubbly, shallow cinematic creature that exists solely in the fevered imaginations of sensitive writer-directors to teach broodingly soulful young men to embrace life and its infinite mysteries and adventures."
The song that plays at the start of the road trip to Snot's dad's funeral is California by Delta Spirit.
