The gaunt, haggard stranger, known only as 'X', stood on a box in Trafalgar Square and announced he had come from the year 2057, where Terminator 328b: Big Robot Wank Thing has just gone on general release.

He said: "If you thought Terminator Salvation was a steaming pile of cinematic mule dung, this latest one is like being raped through your eyes by an army of insane monkeys.

"Terminator 328b is directed by McB, a genetic hybrid created from a mixture of McG's frozen semen and beaver DNA.

"It's about how John Connor's father's son's grandson's uncle's niece's nephew goes back to the future to shag his own nan, thus preventing the first calculator from being made. Or something.

"The main baddie is a big robot steam train with wings and a tail that flies around shitting nuclear bombs. It is played by Eddie Murphy."

X added: "And then there's a chase scene, but it's on tricycles, it's two days long and you're not allowed to go for a piss."

Before collapsing from exhaustion, X warned that in the future Terminator films are beamed directly into your cerebral cortex, often as part of a triple bill including Batman's Big Momma's House 18 and Indiana Jones and the Inner Tube of Hercules.
