Stop me if you've heard this one before.
TV personality claims he's burned out, wants to move on with his life, will end his fantastically lucrative run on a primetime TV show because "it's time" (or something else similarly vague).
95%*: Probability it's just a contract bargaining ploy (ala, Charlie Sheen)
100%: Likelihood the TV media will fall all over itself with the story now, and forget about the earlier claim when the star signs on again.
* would be 100%, but some TV personalities really do foolishly walk away from piles of money (ala, Paula Abdul).
