President Barack Obama and First Lady Michelle Obama had quite the enthusiastic visitor in 106-year-old Virginia McLaurin. When she fulfilled her dream of visiting the White House and meeting Obama for Black History Month, she danced with joy, eventually getting the Obamas to join in. "What's the secret to still dancing at 106?" Obama asked, and McLaurin replied, "Just keep movin'." Watch the sweet video above, and then see the funny clip of Obama that went viral [3] last week.
