Because when you saw it you walked 360 degrees away

360 is a full circle, e.g. you'd turn right back toward it.

Let me help you--that's the joke.

As a teenager circa 2007, I would troll in World of Warcraft's Trade chat with a variant of this joke.

360 degrees away? Why don't you try this and see how far you get. Look at something now turn a full circle (360 degrees) and start walking, become amazed that whatever you were looking at is now closer.
