OMG. Do not watch this unless you're willing to flail in public. So f*cking funny. Lots of Jeremy being his derpy self, but my fave parts are:
1) Maria Hill channeling Cobie Smulders channeling Robin Scherbatsky ("Coooooooooulllllsoooooooooooooooon")
2) Thor's mishandling of Mjölnir (it's like a graceful dance)
3) Bruce Banner abandoning the rest of them to their doom (which is so what I'd do)
