This is taken from Genius about Comfy in Nautica "We’re all new to it. Everyone lives it differently and we need to embrace our individuality, taking what we like from mass culture, and, alternatively, from our own mind and perceptions which influence our life decisions."

They reference a "Lincoln" in Kids on Holiday to better tell the story. "When his parents are yelling..They ordered a Lincoln..And they received a compact".
