John: Even though he doesn't even want to go out for Halloween, you force him to dress up in a couples costume with you. This year, you're the red crayon, and he's the blue crayon. Together you make purple.
Paul: Halloween is fun for the both of you, there's always parties to go to, and get drunk at. So Paul picks out a scary werewolf costume, while you go with a quick witchy countess costume.
George: I think everyone saw this coming, but George wanted to go as a vampire this year, no need to waste money on fake fangs, his canine teeth already make him look like one. The entire night, through the party he's socializing with everyone, drinking a bit as well. And every now and then he might come up behind you and whisper something seductive into your ear and tell you he's going to bite you when you get home.
Ringo: Ringo loves Halloween, mostly because of the candy and how cool it is to dress up. If you dont want to go, that's too bad, you're going anyway. And in matching costumes. He'll dress you up in a little devil costume (and refer to you as that, 'little devil' all night) and he'll go in an angel costume. But he prefers if you not call him angel.
