No, Tony didn't take himself super seriously. Well, not usually anyway. Only when it called for it in the moment, but just about everyone was like that.
So. Yeah. It was funny and Tony saw that it was. It was also weird, because apparently that meant that Bucky had thought about him at least a little in a way that wasn't negative, and where he'd wanna be able to deal with a goat that had his name attached to it all the time.
"I'm making goat sunglasses. It's seriously next on my list of projects. I deserve a day off, and Tony needs to pull his weight. I'll come by for the meet and greet and fitting some time next week. Have the goat pencil it into his schedule. Hey, flex your arm for me, wiggle your fingers. Let's see it in action again."
