Several years ago on this very blog I introduced the concept of fanesia. That's not a new soft drink or an 'American Idol' contestant, it actually stands for 'fan amnesia,' those TV moments that we refuse to acknowledge even happened on our favorite shows. Past examples I've used have included Fitzwallace dying on 'The West Wing,' the last episode of 'Seinfeld,' Mark dying on 'ER,' and 'Will & Grace' not speaking to each other for years in their final episode. In my mind, those things never happened on those shows.

Here are four more. Let us know your favorite Fanesia moments in the comments.
