The Marvel Dubsmash Wars Are Back — And They’ve Got Miss Piggy

The best part is, it's all for a good cause. And not just "our enjoyment," either.

Far and away, the most insane part of this year's San Diego Comic-Con was when the stars of "Marvel's Agents of S.H.I.E.L.D." and "Marvel's Agent Carter" went head-to-head in an all-out Dubsmash war. Seriously, Haley Atwell and Clark Gregg did not pull their fabulous lip-syncing punches -- and when Atwell and co-star James D'Arcy literally flew across the country to enlist the help of Captain America himself, we thought it was all over.

Well, the battle ended, but the war is only just beginning... and this time, the stakes are even better.

Last week, Team Carter and Team Shield joined up with Crowdrise to announce that they'd be bringing back the Dubsmash wars once again, only this time you get to choose the winner by donating to charity -- Stomp Out Bullying for Team Carter, and St. Jude Children's Research Hospital for Team S.H.I.E.L.D. Plus, donating will also enter you to win the chance to join all the competitors in a Dubmash video together. Be still my Marvel nerd heart.

Today (September 2) the competition starts for real, and Team Carter is already pulling way into the lead by snagging fellow ABC star Miss Piggy to help. They also picked the best song ever, just sayin'.

You can only view the videos at their Crowdrise site, so be sure to head over there to check out how the battle continues. Calling it now, we're preeeetty convinced The Rock will make an appearance at some point. Either way, it's bound to get pretty ridiculous.
