Red Dwarf episode Beyond a Joke:

From wikipedia: Starbug passes an old derelict spaceship, the SS Centauri, which Kryten scavenges for supplies. He finds some live lobsters in stasis and brings them aboard to cook a fine supper. This is convenient, since it is exactly five years to the day since Kryten was rescued from the wreck of the Nova 5 and he was looking for a way to celebrate the anniversary. Meanwhile, Kochanski (Chloë Annett) decides to educate Lister (Craig Charles) and Cat (Danny John-Jules) on the finer points of etiquette by introducing them to a virtual reality rendition of Pride and Prejudice Land in Jane Austen World. Kryten’s plans for a lobster supper, which he had been preparing all day, are scuppered by this. Kryten’s jealousy gets out of hand and he enters the virtual reality simulation in a tank to spoil their fun and compel them to return for supper.
