Did you know that Tuesday (March 6) was the 100th birthday for the Oreo cookie?
Lady Antebellum helped celebrate with a surprise concert at the Grove  shopping area in Los Angeles. "We are so excited to be a part of Oreo's 100th birthday celebration at the Grove!" the group posted on its Facebook page.
That show happened after several dozen folks in all black—and one giant Oreo cookie—danced around in a flash mob in the same area. Similar flash mobs broke out in six other cities around the country.
But no giant glasses of milk joined in on any of those mobs.
