Weird flex by Freeman, IMO. Franklin was just being Franklin. He's a little douchey and that's part of his personality. Can't say if he was trying to talk down to Freeman or not. When I read the hairline comment, I thought he was being self-deprecating about being bald.

This story reminded me of Apollo Creed and Ivan Drago:
