Tony Stark: Sh*t!

Steve Rogers: Language!

(Some chatter and fighting later…)

Tony Stark: Wait a second. No one else is gonna deal with the fact that Cap just said “Language”?

Steve Rogers: I know. Just slipped out.

(Some more chatter and fighting later…)

Thor: Find the scepter.

Tony Stark: And for gosh sake, watch your language!

Steve Rogers: That’s not going away any time soon.
