What’s your best visual explanation or metaphor for a pointer?

I’ve seen a lot of people struggle to really “get” pointers as a concept.

If you had to visually or metaphorically explain what a pointer is (to a beginner or to your past self), how would you do it?

What’s your favorite way to visualize or describe pointers so they click intuitively?
