Today is Sadie and Yossel's 60th wedding anniversary. They have lived in the same flat all this time and Sadie, being very frugal, has always handled the family finances. But unknown to Yossel, for each and every day of their 60 years together, Sadie has been putting some money aside. 

And now, on the day of their 60th anniversary, Sadie tells Yossel about her secret savings and that she has a big surprise for him. They drive to a new neighborhood and she takes Yossel to a brand new high-rise apartment.  The elevator takes them to the penthouse where Sadie gives Yossel the keys to their new flat.

It's magnificent. It's not only furnished with the finest of modern furniture and décor, but it also has large glass windows, a wrap-around balcony, and has views over the entire city. Sadie asks Yossel to look around the flat while she opens a bottle of celebration Champagne.

Yossel returns 10 minutes later raving about each and every new room, appliance and expensive art work on the walls. 

"Sadie," he says, "you’re magnificent! The dining room is marvelous. In fact everything is fantastic. I've even just been to the bathroom - it’s all shiny, white, and has lovely cupboards everywhere. And when I opened one of the doors, the light went on automatically. And later, when I closed the door, the light went out."

"Yossel," says Sadie, "don’t tell me you pished in the refrigerator?"
