Do you think anyone’s told Steve Rogers about Firefly yet?

“You want to see Captain America and Tony Stark not like each other, articulately. Writing them was where I started. They represent two polar opposites and I’m basically Tony and I wish I was Steve. I believe everything that Steve says, but at the end of the day, I’m more like Tony, without the brilliance and the billions.”
Joss Whedon (x)

Steve Rogers: “Is everything a joke to you?” 

Tony Stark: “Funny things are.”
