Falcon also gets to deliver one of the film's coolest Easter eggs, when at the very end of the movie, he says to a journalist, "We got a guy who swings, we got a guy who climbs up the wall". It's far too blatant to not be a reference to Spider-Man, and whether or not it was intentional (given that Spidey possibly wasn't confirmed to join the MCU when this scene was shot), it fits in beautifully given Spidey's upcoming adventures with The Avengers. It's one that'll fly over the heads of many, but if you caught it, it's truly a "Holy s***!" moment.
