Thanks for the Memory (Red Dwarf)

On a Saturday night, while the Red Dwarf group hold a party for him on the anniversary of his death, Arnold Rimmer drunkenly confides in Dave Lister about his time with the ship's female boxing champion, Yvonne McGruder, and how it was the only sexual encounter he ever had. Rimmer admits that, while he opted to put his career over his personal life, he would trade it all in just "to be loved, and to have been in love." When he, Lister and Cat wake up after the party, they find it to be Thursday rather than Sunday. The group quickly find several odd things – Lister's jigsaw puzzle he had been working on is solved; several pages from Lister's diary are missing; both Lister and Cat have broken a leg each; Holly's star charts he was mapping have been messed with, and the ship's black box is missing. To solve the mystery, the group trace the black box by its signal on a barren moon, buried in a shallow grave next to a giant footprint and marked by a headstone that reads "To the memory of the memory of Lise Yates". Returning to the ship with the black box, the group review its footage and discover what happened over the past few days. After feeling sorry for Rimmer, Lister visited the Hologram Suite intending to give him a present, uploading a memory of his own recounting his eight months with Lise Yates (Sabra Williams), an old girlfriend, and making it one of Rimmer's. The following morning, Rimmer woke in a jubilant mood but questioned elements of his new memories he now had. His happiness was soon broken when he found Lise's letters to Lister and assumed she was dating them both, ==Production==

A quarry in Wales was used for the location of Rimmer's death-day opening scene for the episode. The live action footage of the scene was merged with model footage of Blue Midget and Red Dwarf, which was seen in the distant background. During the pre-record filming of the episode, Craig Charles's then-wife was giving birth to their son Jack; Craig filmed the scenes where Lister's face was visible as quickly as possible and then rushed away to be at the birth of his son (arriving twenty minutes late). The remainder of location shooting, in which Lister was wearing a space-suit, had production manager Mike Agnew as the double for Lister. But in fact the plaster cast couldn't fit Agnew's foot as he had bigger feet than Craig Charles – a close look at the episode would reveal that there are several frames in the episode where neither the Cat nor Lister (stood in by Agnew) had casts. To film Lister's drunken pilot skills on the flight back to Red Dwarf, wires were used by the model team to give the jerking motion. The one guest star was Sabra Williams who plays Lise Yates. ==Similarity to Star Trek: The Next Generation==

In their book The Red Dwarf Programme Guide, Chris Howarth and Steve Lyons point out the "uncanny similarities" between the Red Dwarf episode "Thanks for the Memory" and the Star Trek: The Next Generation episode "Clues", which aired on American television nearly two and half years later. Howarth and Lyons note that the American show "has the cast waking up to find that time has passed of which they have no memory. Despite the resistance of their mechanical crew member, they attempt to find out what has happened, but learn that they were better off not knowing. One of them even has a broken limb..." ==Reception==

Originally broadcast on the British television channel BBC2 on 20 September 1988 in the 9:00 pm evening slot, the episode was voted by readers of the Red Dwarf Smegazine in a 1992 poll as the 19th best episode of the 30 then existing, attracting 1.9% of the vote. This made it the fifth-ranked of Series 2's episodes. However, director Ed Bye stated in the Series II documentary, "It's Cold Outside", that the episode was a standout of the series. ==Remastering==

The remastering of Series I to III was carried out during the late 1990s. Changes throughout the series included replacement of the opening credits, giving the picture a colour grade and filmising, computer generated special effects of Red Dwarf and many more visual and audio enhancements. ==Notes==
