Quote from Ross in The One with the East German Laundry Detergent
Ross: Hey, why don't I just join you both there? Rachel: Don't you have a laundry room in your building? Ross: Yes. I do have a laundry room in my building. But there's a rat problem. Apparently, they're attracted to the dryer sheets. And you know, they're going in fine, but they're coming out all fluffy.
