Blue alert

One of the Funniest scenes in television, this originates from the BBC Sci-fi sitcom Red Dwarf the episode is S6E2 titled Legion and it goes like this;
Rimmer: Go to Blue Alert.
Lister: What for? There's no one to alert, we're all here.
Rimmer: I'd just feel more comfortable if we were all on our toes because everyone's aware it's a Blue Alert situation.
Lister: We all are on our toes!
Rimmer: May I remind you all of Space Corps Directive 34124?
Kryten: 34124. "No officer with false teeth should attempt oral sex in zero gravity".
Rimmer: Damn you both, all the way to Hades! I want to go to Blue Alert!
Lister: Okay, okay.
He presses a button; a sign reading 'Alert' in blue lighting begins flashing pathetically in the corner of the cabin
Rimmer: Thank you. A bit of professionalism.
...
Rimmer: Step up to Red Alert!
Kryten: Sir, are you absolutely sure? It does mean changing the bulb.
