You'll understand once you watch this:
TMZ has put together this excellent highlight reel of a recent 4 1/2 hour deposition hearing where the Biebs is being sued for allegedly ordering his bodyguard to beat up a member of the paparazzi.
The mashup includes all of Bieber's antics during the hearing which are likely to make your head spin. One of my favorite "arguments" he had during the hearing: "How could I ever be aware of something, knowing something? That's physically impossible."
