There was a post a couple months ago about it... but just in case people missed the episodes...
The wedding was just on Sunday (it was honestly the first time I saw it... I'm ashamed to admit that I quit watching the Nanny before it ended... I don't know why, because I always loved it) and it'll be on again Thursday night/Friday morning on Lifetime (of course) at 12:30 and 1... which was weird to me, so check, just in case it changes.
