This was intended as a meme but is actually a good representation of what "Null" is. In C#, when you declare string s = "My shit"; it means that "s" is a reference to a memory location that holds the data "My shit". string s = null; means that the reference "s" exists but it's not pointing to any object, as in it holds nothing.

Please help me explain like I'm five what Null is and how it differs from the empty string.
EDIT: I love the analogy. This is a good explanation. Answer
