Take a tv series and add your own plot twists that would totally sink the show and send its viewers scrambling to change the dial. The show may be successful or it may be well on its way to screwing itself over anyway (but hey, why not speed up its demise?).
Ones I thought up for Breaking Bad:
Walt comes home and discovers, to his surprise, that the whole family wants in on the meth-making business. Everyone (including the baby) is dressed up in yellow suits, ready to start cooking.
Towards the conclusion of the series, a nervous Jesse decides to do one last cooking session with Walt. When he arrives at the lab, the lights are all off. When he flips on the lights, all of Walt's family (including Hank and Marie) shout "SURPRISE!" and Jesse sees that Walt has set up the whole meth-cooking scheme to get Jesse to learn about chemistry. A very confused Jesse is embraced by Walt, who tearfully exclaims how proud he is of his ex-student, and has a celebration cake for Jesse along with balloons, party favors, confetti and streamers.
Wow, that would pretty much guarantee the end of the series, as no one would watch anymore.
What stupid/funny plot twists could YOU add to a series (old OR recent) that would eff it up irreparably?
