My favorite items from the Oakland A's list of prohibited items

Went to the A's game yesterday. Was presented with a list of prohibited items. Here are my favs.
  1. Ball retrieving devices
  2. Brooms / Sticks / Poles (Exceptions: Wooden drumsticks and flag sticks. Brooms are allowed for potential A's sweep of series.)
  3. Bubble machines
  4. Clothing with vulgar languages or images
  5. Laser lights & pointers
  6. Portable chairs
  7. Projectiles (including inflatable balls & frisbees)
  8. ...and here's the whole list. It's a great list.
