Enjoy the next fifty years, Murr!
I can kind of see your fiancée's point, though. We all know the classic episodes of The Simpsons by heart by now, and the newer episodes are so bad I'd probably hang myself rather than have to watch them every day. On the other hand, if all you're going to do is watch Friends, you may as well be engaged to Diego!
You should try watching The Big Bang Theory. Then you'd both suffer.
