NSR: Who's on your list?

For those of you that watch Friends who would be on your list of 5 (and ONLY 5) people that you could sleep with and it wouldn't count? IE you and your spouse/fiance/boyfriend/girlfriend/significant other/life partner/ whatever you want to call it have an agreement that if you ran into one of these 5 people you could sleep with them and it wouldn't count. (of course no one here would actually cheat). I'll have to think about my 5 and get back to ya'll...
