British sailors who have been at sea longer than expected are spreading holiday cheer to the world, with a little help from Mariah Carey's Christmas classic, "All I Want For Christmas Is You."

A seven-week excursion turned into 225 days away from loved ones, so the men and women aboard the HMS Ocean created this awesome lip-dub that has become an instant YouTube hit.

Mariah Carey showed her support on her Twitter page:  “This is the best thing I've ever seen, you guys just made my day! Happy Happy Christmas!!!”
