The Oakland Coliseum is a place so disgusting and disreputable, it is similar to the sort of unsanitary hole in the ground that your average orc calls home. When you talk about the Coliseum, you are talking about routine floods of sewage, groundscrews who forget to put tarps down, no bullpen (the relievers just warm up in foul territory), and a group of fans who make the bleacher creatures look like a church qoir.
(They generally wear green for A's games).
Like orcs, the A's seem to spawn like mushrooms out of the ground. They appear out of nowhere, with no obvious beginning or ancestry. Case in point: Jesse Chavez. Who is he, and where did he come from? Why is he good? The correct answer is that Billy Beane grew him in a dungeon somewhere, just like all the other orcs.
(Is this Jesse Chavez?)
Like orcs, the A's are green.
(Eric Sogard without his glasses)
Like orcs, the A's answer to a dark wizard. Not showing the least amount of intelligence themselves, they at least know someone who is.
(The Green Wizard)
Like orcs, the A's are fungible like bales of hay. One orc is about as good as the next, and the turnover for the horde usually means that the same creatures are not there from year to year, yet they maintain a uniformity of identity.
(Don't try to differentiate them. You'll only confuse yourself)
