Why did they call it the Xbox 360? Because when you see it, you turn 360 degrees and walk away.

If you turn 360 degrees, you end up facing the same direction you were in before the turn. A U-turn is a 180, not a 360. That is why in great grandparent, "did a complete 360," does not mean what the writer thinks it means.
