Red Dwarf, Series V

[discussing the looming 3 months in quarantine]

Kryten:
Sir, it's a scientific fact that the human male needs to spend time by himself

Lister:
Is it?

Kryten:
Hm, the most popular pass times have always been ones that males can enjoy alone. Angling, golf and of course the all time number 1

Cat:
I's not just humans, look what happens when two male tigers are locked up together. One of them winds up on the others toothpick

Kryten:
Lions, tigers, scorpions, rats. Even vultures when they're in captivity.

Lister:
What are you saying to me? 'Vultures need personal space'? They need time alone to put their feet up and read 'What Carcass?' magazine?
