In the months before Jennifer Briskin and Austin Tansantisuk's big day, lots of planning and preparation went into making sure their Atlanta wedding would be a memorable one.

What color will the bridesmaids' dresses be? What song will the bride walk down the aisle to? Who will be the flower girl?

But Briskin, 29, broke tradition when she asked her 85-year-old grandfather to be the "flower girl" at her Oct. 1 Buckhead wedding.

"It really started out as a joke," Briskin told The Atlanta Journal-Constitution.

"I knew I wanted him to play some special part in my wedding, because he’s so special in my life," she said. "But if you think of traditional roles in the wedding, there's nothing special for a grandparent to do, and I just wanted to highlight him in some way."

Briskin officially asked her grandfather, Stanley, to be her "flower grandpa" a few months before the wedding in a message she had embroidered on a handkerchief.

"Papa, will you be my flower grandpa? Love, Jen," the message read.

On the day of the wedding, Stanley (who didn't want his last name published) was the last person to walk down the aisle before the bride and her parents. And wedding guests had no idea what was in store.

"I could see a little of what was happening just before I walked down aisle," the bride said. "But all I heard was constant laughter."

Her grandfather had been so nervous and was getting cold feet about his role, but Briskin kept telling him that if children can do this, he can, too.

On the day of the wedding, he was a little overwhelmed and couldn't quite remember everything he practiced. Instead of throwing flowers down the aisle, he ended up throwing them on guests.

But with all the laughter and joy he brought by being a stellar "flower grandpa," Stanley soon became a celebrity at the wedding.

Everyone wanted a moment with him.

It was still Briskin and Tansantisuk's big day, but with all the attention everyone's favorite "flower grandpa" has received,  Briskin said he's totally stolen the thunder.

"The reason that this is so fun to me is that my grandpa is very caring and spends most of his time doing work for people less fortunate," Briskin said. "He doesn’t like being in the spotlight typically, so it was nice to put him in the spotlight for a memorable moment like this."
