The Hawkeye's farm thing is from a leaked clip featuring Tony Stark and Steve Rogers discussing ... I'm trying to remember how it started but it ended with Steve saying that trying to end wars before they start gets innocent people killed, so. That type of discussion. It also ended with cranky Steve Rogers ripping a long in half, which is at least half of what Tumblr is getting so excited about.

The clip I saw, though, was filmed by hand off a phone probably in a theatre, so it might have been taken down by now if it wasn't intended to be leaked.
