The Oakland A’s will give away 15.000 MC Hammer bobbleheads on July 17. (

The Major League Baseball season is a grind. And with 81 home games a year, it’s also a serious test of creativity and ingenuity for team organizations looking to keep fans lining up at the gates, even in the dog days of summer.

After studying the pitfalls of the Cleveland Indians’ infamous 10-cent beer night, the Washington Nationals did bang-up business earlier this season with Dollar Monday, featuring $1 tickets, hot dogs, peanuts, popcorn and parking. Next up for the Nats: Jayson Werth bobblehead night.

Well, it appears the Oakland Athletics are taking the bobblehead craze to a new level when they don their parachute pants and hand out 15,000 MC Hammer bobbleheads on July 17 as part of the team’s “80s weekend.”

Hammer — a former A’s batboy ( who knew? ) — will be on hand to throw out the first pitch. The A’s are asking fans to “come dressed in your freshest gear.”

The Hammertime throwback is enough to remind one of other great moments in retro bobblehead history.

Like this 1980’s themed Adam Dunn bobblehead (which looks more like the lovechild of David Letterman and Steve Butabi) released by the Cincinnati Reds in 2008.

Here’s a look back at some of the best MLB promotional giveaways from the 2010 season.

Now stop... Hammertime!
