Hawkeye apparently scrapped a post-credits scene with that Rockefeller Center owl
The show ultimately went with something "light" in honor of Christmas, but that wasn't always the plan

Disney+’s Hawkeye already completely rewrote and improved the post-credits scene of the Black Widow movie, maintaining a Marvel Cinematic Universe tradition where the stingers in the credits are total must-see events that also don’t strictly matter all that much for future movies (we got into that a bit in this piece), but when it came time to do a post-credits scene of its own in season (series?) finale “So This Is Christmas?” this past week, Hawkeye refused to play that game.
Instead of a traditional tease that ultimately gets rewritten by a future story, Hawkeye offered a little gift for MCU fans with a full performance of a song from the Broadway show seen in the show’s first episode, a completely ridiculous Avengers musical number that Marvel Studios definitely thinks is funnier than it actually is. (It’s not not funny, to be fair.)
