"As America prepares to celebrate the 50th anniversary of the moon landing, we want to give our fans a new taste experience that is out of this world," Skena continued. "We choose to fill our Original Glazed doughnuts, not because it is easy, but because it is hard (no disrespect intended, JFK). Actually… it's not hard, it's melt-in-your-mouth delicious."
