When you are listening to the radio in bed and you hear them say either 'Beatles', 'Paul', 'John', 'George', 'Ringo' ... anything to do with the Beatles - you immediately sit up and turn the light on and get out of bed so you can mouth the words and dance around, even if it's midnight.
When somebody says 'Beatles' you go up to them, even if they're complete strangers, and start a conversation.
When you step on a beetle, you say: "Oh no - I killed George!" and try to revive him.
When you get a big red cross on your homework for spelling 'beetle' wrong. I spelled it 'beatle'
