While browsing the Red Dwarf wiki I found this little tidbit on the page for “Siliconia”:
Oh, I never noticed that, ow my heart. Here’s the scene in question from “Siliconia”-
RIMMER: I like being a mechanoid. I don’t have to become an officer anymore, compete with my brothers. Envy, ambition, that acid ball of resentment I carried around with me the whole time, it’s gone.
LISTER: We have to get your neuroses back!
RIMMER: But sir, I don’t want them back.
LISTER: Then what makes you you?
RIMMER: I don’t want to be me. I want to be a mechanoid, programmed to serve. Sometimes when I was young I’d sit for hours staring at our fish tank feeling envious.
CAT: You wanted to be a fish tank?!
RIMMER: I wanted to be a fish. They had food, a small rock to swim in and out of, they didn’t have a care in the world.
CAT: That’s cos I wasn’t there!
RIMMER: Those little fish, they’d never know what it was like to fail and disappoint. They’d just swim around in circles, not a thought in their heads. And it’s the thinking that causes all the pain.
And way, way back, thirty years ago, during the very first episode of the show-
LISTER: Not until you pass your engineer’s exam. And you won’t do that
because you’ll just go in there and flunk again.
RIMMER: Lister, last time I only failed by the narrowest of narrow
LISTER: You what? You walked in there, wrote, “I am a fish,” four
hundred times, did a funny little dance, and fainted.
RIMMER: That’s a total lie!
LISTER: No, it’s not! Petersen told me.
RIMMER: (Mocking LISTER) “No, it’s not! Petersen told me.” Lister, if
you must know, what I did was, I wrote a discourse on power circuits
which was simply too radical, too unconventional, too mould- breaking for the examiners to accept.
LISTER: Yeah. You said you were a fish.
The Siliconia speech might not even have been an intended nod to continuity, but dang… Rimmer is only happy when he’s a fish.
