John: When you feel sad and you feel like crying, you lay on your bed and listen to John's song "Imagine" until you fall asleep. Sometimes it makes you cry either way.
Paul: Ask for hugs from Paul and try to get whatever is making you sad off your mind by following him everywhere and holding his hand.
George: Ask George to sing you something or play you something sweet to make you happy. Which he gladly does because he's George and he loves his wife :)
Ringo: Eat chocolate and lay your head down lazily on his stomach on the couch until you either cry or fall asleep.
