After seeing his wife tear up watching someone on television use a flash mob to propose, Carl Gilbertson made a mental note to do something similar for their 10th anniversary. He pulled off the feat and a video of the accomplishment is now making viewers around the world tear up along with Gilbertson's wife, Laura, who has multiple sclerosis. Gilbertson ... recruited students from a local performing arts college to serenade Laura as part of a flash mob that sang Just the Way You Are" by Bruno Mars. "When we met, although having MS, she was fully able bodied, worked as a children's nurse and we'd been together for a little while before she even told me, because it no [was] big deal," Gilbertson, 38, explained. "So the song was important only in the sense that I wanted her to know that no matter what may change, I love her just as she is and that to me she's perfect." The couple met 15 years ago. Although Laura experienced occasional MS relapses back then, "she always bounced back," Gilbertson said. Shortly after the Gilbertsons returned from their honeymoon, Laura experienced a serious relapse that was more difficult to recover from. A few months later, she retired from work and began using a wheelchair. "I guess I wanted to make a fuss of our 10th anniversary because she's been so brave in fighting back," he said. The video shows her getting overcome by emotion, particularly by the end of the song when the group unrolls a banner that says, "Happy Anniversary Laura."
