Five years after Mickey Mouse appeared in blackface (see: Mickey's Mellerdrammer), he befriends a native African. Well, we guess we should say he saves a character that Disney Wiki describes as "monkey face" from his brother who put him up for dinner that day, because they're cannibals. After Mickey saves him, and he bows down to Mickey to get a pat on the head and an "Okay big boy," Mickey names him, gives him a top hat, and says, "Hey, you be my man Friday. You Friday. Me Mickey." Thanks for the name, white man. Friday even gets to tap dance a little.
