It's one thing when a derisive T-shirt is produced by fans. It's another when that shirt is created and sold by the licensed apparel manufacturer of a league.

Oakland A's fans aren't too happy with a new T-shirt being sold by Majestic, MLB's official apparel manufacturer. The $22 shirt, pictured below, has both the Giants' and the A's' logos, but above Oakland's elephant the text reads: "Nobody Talks About the Elephant in the Room."

Too far? Maybe. But as Casey Pratt of CSN Bay Area notes, the A's aren't exactly innocent in this Bay Area battle. A few years ago they put up signs with the phrase “Zero Splash Hits, Four World Titles."

Since then, the Giants have won two World Series.
