So this old couple goes to Germany for vacation, and they're doing the whole tour.
And they get into a big fight on the bus, and they go on the tour of Auschwitz and they're not speaking to each other the whole time.
They get back on the bus and the husband says "You were right, I was wrong, I'm sorry."
And she says: "Oh, NOW you're sorry. Now that you ruined Auschwitz for me."
