John: Drinks until he can hardly walk and has to sit down or waits until he passes out on the couch.
Paul: Providing entertainment, playing the piano, starting a dance competition, or acting silly.
George: Dancing with you even if you don't want to. He'll grab you by your arms and start twirling you and country dancing like a fool.
Ringo: Even though he resents alcohol most of the time, he might drink a bit and sing a lot.
