Specific: Loki's been causing mischief on earth for a long time
I'm looking for a fic that I can't for the life of me find.
So Loki's been traveling to Earth since forever, and everyone knows of him because he constantly causes harmless mischief around the globe. He helped fight during World War II with Cap and turned Hitler into some sort of animal(?) during one of his speeches. He also mopes in SHIELD's ice cream freezer when he learns of his true heritage and invites Cap to mope with him and Natasha, who was already in the freezer before Loki locked both of them in it.
Does this sound familiar to anyone? Thanks.
