The crew of the Royal Navy’s HMS Ocean came up with a creative way to announce their Christmas homecoming after seven long months at sea. In a series of giddy antics, they lipsynced their way through Mariah Carey’s rendition of “All I Want for Christmas.”

Last April the HMS Ocean was sent out for what was supposed to be a seven-week training exercise, but suddenly got diverted to Libya instead to support the UN air mission during the uprising against Moammar Gaddafi. When the crew finally got word that they’d be back in their home port of Plymouth for Christmas, they celebrated by making their own video during an unusually quiet two-day period. A morale booster for the crew, the video is silly, funny and a “feel-good” way to usher in the holidays. Welcome home.
