Centenarians have all sorts of unusual tricks when it comes to leading a long, happy life. For Susannah Mushatt Jones, a 116-year-old Alabama native who passed away earlier this year, the secret was eating bacon, eggs, and grits each day. For Agnes Fenton, a 110-year-old from New Jersey, the key was drinking three Miller High Lifes every 24 hours. And though few would consider the Golden Arches the Fountain of Youth, a 100-year-old from Hanover, Maryland named Nadine Baum will now be able to live out the rest of her days eating free McDonald’s.

On Thursday, Baum walked into her local McDonald's like she does most days, using a walker, and followed by her son, Mike. Unlike most days, however, Thursday marked Baum's 100th birthday, and everyone inside the restaurant knew it, decorating her regular, window-side booth with flowers and balloons.

According to the Evening Sun, nearly the entire staff of the Baltimore Street McDonald's was on hand to sing Baum “Happy Birthday.” Crew-members Ginny Slaubaugh and Genevieve Steinbrenner planned the surprise party, which included a cake, a card, and one very special gift: free Mickey D's for life.

Baum and her son have been going to the Baltimore Street McDonald's for lunch for almost six years. More recently, however, Baum's health has started to decline—with arthritis making it difficult for her to get around—but she still makes it to her favorite fast-food spot as much as possible. Arthritis or no arthritis, you know she had to show up for her big birthday party.

"I don't know what I did to deserve all this," Baum told the Evening Sun. "I count my blessings every day."

Let's hope Baum has figured out how to use Yelp, because those staff members deserve one helluva review.
