[Grizzled Bear]

Rimmer ya smeghead! You blame everything on Aliens. Last week you blamed the missing bog-roll on Aliens!

[null and void]

RIMMER: (Snaps his fingers) Aliens!
LISTER: Oh god, aliens? Your explanation for anything slightly peculiar is aliens, isn't it? You lose your keys -- it's aliens. A picture falls off the wall -- it's aliens. That time we used up a whole bog roll in a day -- you thought that was aliens as well.
RIMMER: Well we didn't use it all, Lister. Who did?
LISTER: Rimmer, aliens used our bog roll?
RIMMER: Just 'cause they're aliens doesn't mean to say the don't have to visit the little boys' room. Only they probably do something weird and alienesque like it comes out of the top of their heads or something.
LISTER: Well I wouldn't like to be stuck behind one in a cinema.
