As seen in the teaser promo below, Clark has no shame as he sports the flight attendant attire like Britney and works her moves too!

Gregg Atwell 2Clark Gregg will face off against Hayley Atwell (Agent Carter), his Dubsmash rival, in a head-to-head battle of Marvel-ous performances. Their rivalry, and their choice of using lip synching to battle, began at last year’s San Diego Comic Con when they squared off in a Dubsmash war. This ultimately led to a charity initiative that pitted the casts of Agents of S.H.I.E.L.D. and Agent Carter in a fierce, yet fun, competition all for the sake of each show’s desired charity. Agent Carter’s team ended up victorious and was able to raise $79,259 for Stomp Out Bullying. The Agents of S.H.I.E.L.D. was just edged out and raised $75,070 for their charity, St. Jude’s Children’s Research Hospital.
