Make your mind up, people who wrote this show. You'd think that it'd be simple enough to pick one spelling and stick with it, given that Rachel's surname is about as simple as they come. For some reason, though, nobody was capable of committing to a singular spelling on Friends, which resulted in poor old Rachel looking as though she didn't know how to spell her own name. Although it's spelt "Green" in the credits, then, the sign on Rachel's door in Bloomingdale's has her pinned as"Rachel Greene." On Emma's first birthday, though, it's spelt "Green" on a cake box. Have some respect for yourself, Rach - we know you're not the sharpest tool in the shed, but you're not that confused.
