You joke but according to him, Paul McCartney came up with Hey Jude while on the way to visit John as a way to comfort John's son Jules after John divorced his mom for Yoko. Now as a non-depressing song fact, Paul came up with the tune for Yesterday while in bed and was too tired to think of words for it so remembered it as "scrambled eggs" instead of yesterday so he'd remember it in the morning.
