Ross: I still can't believe she hates Pottery Barn.
Rachel: Ross, get over it. It's not like she hates you.
Ross: Yeah, but Pottery Barn? You know what I think? She's just weird, you know. It's because she's a twin. Twins are weird.
Rachel: Ross, she's not weird. She just likes her stuff to be one-of-a-kind.
Ross: Huh. You know what's not one-of-a-kind? A twin!
