Days like these

Some deep chord sounded in me on reading the NYT’s story about the John Lennon museum display in New York capped with this image:

Near the exit is “Telephone Peace,” a white telephone mounted on a wall, with a card telling visitors to answer the phone when it rings.

“This is something we did at the show in 2000,” Mr. Henke said. “Yoko would periodically call in and speak to whoever answers.”

Ms. Ono seemed amused at the prospect. “Yes, you pick up the phone,” she said, “and it will be me.”

Why?
