When did TV shows Jump the Shark / Nuke the Fridge?

As we all know Happy Days lost it when the Fonz jumped the shark, Moonlighting lost the spark when Maddie and David got together, but when have other TV shows had that moment when things began to go terribly wrong?

Prison break flew the coot (spelling?) when they got out of jail ^^

..the first time!

I loved Dexter so much and couldn't get enough of it until the introduction of LILA!!!! I HATED her with a passion and she very nearly spoilt the whole experience for me.

I thought season two started off pretty well, but the series started to lose it as it went on.

Twin Peaks lost its way whenever the murderer was revealed (although the final few episodes did start to find its feet again when the axe fell, shame about that).

Buffy the Vampire Slayer became hit and miss when they left high school.

Firefly jumped the shark when........

...nope. Never had the chance to jump

You know the only good thing about that is that the show is made up of fifteen gloriously brilliant episodes.

I wouldn't say The X Files as a whole jumped the shark, the self contained episodes were always of a high quality throughout its nine years on the air, but the mythology was all over the show that final season.
