"Entangled" is the fourth episode of science fiction sitcom Red Dwarf series X, originally broadcast on the British television channel Dave on 25 October 2012.
The episode was subject to on-set rewrites when it emerged that there were rules and regulations which governed how long performer Peter Elliott could play the role of the chimp without taking a break.
SFX gave it four stars out of five, stating that it was "another cracking episode absolutely filled with comedy gems ... the gag rate is so fast you're in danger of whiplash, and the barmy central plot twists and turns so much you never know [what] bizarre situation you're going to witness next.
"[1] Radio Times called it "a smart, inventive episode," and reserved particular praise for the skill of Danny John-Jules (Cat) and Robert Llewellyn (Kryten) "who, as a result of a quantum entanglement, have to deliver their lines in perfect unison.
"[6] IGN awarded the episode 7.2 out of ten, stating that although the pace was "a little pedestrian at times," there was "enough smart plotting and good gags to ensure it maintains the high standard of this 10th season.
"[7] Starburst gave it eight stars out of ten, and called it "the best episode of the series since the opener "Trojan" and said that "the whole idea of having the crew go off on an adventure, meet strange life forms and at the last minute figure a way out of a tricky situation with some absurd logic, really gives the proceedings a classic Dwarf feel.
