"I have an army." "We have a Hulk." And we just had a geekgasm. We've got the exclusive debut on a brand new "Avengers" clip featuring Tony Stark exchanging zingers with Loki, the God of Mischief. It's light on the action, but heavy on the awesome. Robert Downey Jr. and Tom Hiddleston are in top form in the scene, and we're dying to see more from the two of them. You'll be dying too once you've watched the clip. Stop dilly-dallying and get to it by clicking on the player below!
