It's not an analogy. It's just psychology. Your brain is wired to activate areas that are attached to each other. A smell from your childhood evokes a physical response in the brain that makes you happy (or sad, depending on the childhood).
It's the same with a celebrity. You physically feel good when you see that celebrity because in the past you felt good when you saw that celebrity.
