A neon sign that has drip, drip, dripped its message—"The Leak Stops Here"—on Los Angeles' Westwood Boulevard for 60 years is coming down next month.

The animated Clayton Plumbers sign is too expensive to maintain, says its owner, Jim Bacon, who bought the building in 1979 and paid $20,000 to restore the 1947 sign six years ago.

"It got too costly to maintain. It was over $1,000 a month," Bacon says. "I finally said, 'No, I'm not going to do it anymore, that's it. I'm taking it down.'"

A crew will remove the sign, which is about 20 feet tall, on April 16, Bacon says.
