In this week's top 10 viral videos that had everyone buzzing: Ricky Martin strips down -- way down -- in a new tour promo clip, Mary J. Blige sings "Stairway to Heaven" on Oprah, Death Cab for Cutie take us out to the ball game, Snoop Dogg chops trees with Kid Cudi, Tea Party rappers apparently exist, and more. 

1) Ricky Martin's Naked Truth

In a promo video for his upcoming "Black & White" tour, a fully nude Ricky Martin curls into the fetal position as phrases like "Change Your Life" and "Peace Is Born Within"  appear in ink across his body. Martin recently announced that he's gay after years of speculation over his sexuality, and many are seeing this video as another sign that he's ready to embrace his new truth. That, or he just wanted to show off his pecs. 

Bonus Freedom Cry: In the Flaming Lips' new clip for "Powerless," a confused monkey looks on as a kidnapped woman busts out of her schackles...with her mind! (Watch) 

2) Death Cab Takes Us Out to the Ball Game

Seattle rockers Death Cab for Cutie show their support for the home team by playing "Take Me Out to the Ball Game" and John Fogerty's "Centerfield" at the Mariners' season opener, confusing hipster fans who didn't realize it was O.K. to like sports other than kickball. 

Bonus Baseball Gig: Creed frontman Scott Stapp broods and croons his way through the Star Spangled Banner at the Florida Marlins' opener, and it's not entirely clear whether he's being booed or applauded. (Watch) 

3) Mary J. Blige Sings "Stairway to Heaven" on Oprah

The Queen of Hip-Hop Soul appeared on the "Oprah Winfrey Show" this week and covered Led Zeppelin's "Stairway to Heaven." Weird or wonderful? You decide. 

Bonus Cover: Thom Yorke and his new band Atoms for Peace cover the oft-covered Joy Division track "Love Will Tear Us Apart" at a show in Oakland, Calif. (Watch) 

3) Tea Party Rappers: They Exist, Apparently

"U-S-A, everybody get ready/T-E-A, we're taxed enough already/No taxation without representation/the Tea Party movement is sweeping the nation." Need we say more? 

Bonus Politicking: Apparently the creators of the Adult Swim cartoon "Boondocks," which returns May 2 for its last season, think will.i.am is a little in love with President Barack Obama. Except that's not quite how they word it. (Watch) 

5) Snoop and Kid Cudi Chop Trees

Snoop continues to proclaim his love for "That Tree" (not the kind that grows in the forest) in his latest music video, while Kid Cudi wears suspenders, does the robot and talks to a fake deer. Yes, we've come a long way from the days of gin, juice and biatches. 

Bonus Collaboration: Taylor Swift surprises her fans at her Los Angeles concert by singing "Hot 'N Cold," then bringing on Katy Perry herself to finish off the song. (Watch)
