A very old couple comes to the rabbi to get divorced. As tactfully as possible, the rabbi asks the man how old he is.
"103," he replies.
"And you?" the rabbi asks the wife.
"94," she says.
"And how long have you been married?"
"75 years," they say in unison.
"I don't get it," says the rabbi. "After 75 years all of a sudden you decide to get a divorce?"
"It's is not all of a sudden," they reply. "We wanted to get divorced almost 70 years ago, but we decided to wait for the children to die."
