I was just watching Trevor' Life of Sport - hillarious BBC comedy, you there in US probably did't see it yet.
Anyway, in this episode Trevor talks with his son about why he and his wife (boys mother) are drifting apart (exact text is different, just what I can reconctruct ) :
- dad, why are you separated ?
- well, she tells she needs more space.
- Oh, yes, space - the final frontier.
