"But I like being nasty. I like being cranky. Especially if it's a cold day in Chicago, it's nice to just take it out on Kyle, because he's so easy to scream at, you know?"

This quote by Fisher Stevens is an amusing take on the concept of securing one's frustrations on somebody else. He is recommending that it is pleasurable to be "nasty" and "grouchy" when the weather is cold in Chicago, which it is easy to secure these disappointments on Kyle. This quote indicates that Kyle is an easy target for such habits, and that it is a method to make oneself feel better. It is a lighthearted method of looking at a situation that can be hard to deal with. It is a suggestion that it is fine to be cranky and to get disappointments on someone else, as long as it is done in a considerate way.
