As it does every year, Mariah Carey's 1994 holiday hit "All I Want for Christmas Is You" has taken over radio stations and shopping store playlists (not to mention the tween zeitgeist, thanks to a new Justin Bieber duet version). This week, the track took over the internet, too, with a trio of viral videos. (Watch all three below.) Up first: The crew of the British Royal Navy's HMS Ocean — who saw their seven-week tour at sea extended to seven months after a detour to Libya — recorded a cheeky, often shirtless lip-synched version after hearing the news that they'll be home with their families for Christmas. In "Miracle on 42nd Street," an enthusiastic duo performs a campy jazz routine to the song, while in yet another clip, "Dancing With an iPod in Public," brave young Preston Leatherman does just that while wearing a tacky Christmas sweater. Have a look:

"If this doesn't make you feel a little weepy," or at least fill you with the holiday spirit, you may be heartless, says Whitney Jefferson at Jezebel of this clip, which has already earned a tweeted endorsement from Mariah Carey herself. After all, 15 men became dads and five became newlyweds during their detail at sea. With their elaborate, if often skimpy, costumes and truly committed dancing, the crew is clearly overjoyed at the prospect of seeing their families, says Erin Strecker at Entertainment Weekly

This is either "brilliant or insane," says William Goldman at CBS News. For better or worse, however, I was hypnotized. Try brilliant, says Adam B. Vary at Entertainment Weekly. "From their Santa red unitards to their knee-high Christmas stockings, this is just absolutely perfect." The most impressive aspect of their tightly-choreographed clip is that it was shot "Bob Fosse style in one continuous take" — no easy feat:

"Christmastime is for shamelessness," says The Huffington Post. "And it's never been more endearing" than in this video. The best part? The onlookers who stare with "admiration, not embarrassment" at Leatherman's unabashed Christmas joy. Very true, says Vary. What Leatherman "lacks in choreographic precision and filmmaking panache he more than makes up for in enthusiasm."
