A spoof alternative ending of smash US TV series Breaking Bad has been leaked onto the internet, showing its lead character, played by Bryan Cranston, waking up in his former role as Hal in Malcolm in the Middle.

Breaking Bad is the story of a high school chemistry teacher suffering from inoperable lung cancer who turns to drug dealing and a life of crime to earn money for his family.

Waking up from what he thinks is a nightmare, Hal recounts his Breaking Bad experiences to his wife.

But his wife finds his tall tales hard to believe, and tells him: "I told you not to eat those deep-fried Twinkies".
