A standard birthday cake just won't suffice when an icon like Betty White turns 93, and the folks at TV Land did not disappoint on the special occasion. In a YouTube video that's gone viral [1], the comedy legend gets the surprise of a lifetime when a flash mob breaks out in an over-the-top hula dance on the studio lot where Betty films her show Hot in Cleveland. It all started when Betty's costar Dave Foley gave her a ride on a golf cart. What happens next makes Betty smile widely and clap, giving us another peek of the infectious personality that made her special moment with Chris Evans [2] at the People's Choice Awards worth watching on repeat. See Betty's epic reaction — and all the dance moves and costumes! — in the video, above, and be sure to catch up on the latest viral videos [3]. Happy birthday, Betty!
