A Star Trek one, from 'the Undiscovered Country' (I think) - Uhururururu - "well the thing's gotta have a tail-pipe...?!"

And from Hitchhikers Guide...

'Who said anything about panicking, this is still just the culture shock. You wait till I've settled down into the situation and found my bearings. THEN I'll start panicking!'

'Resistance is useless'

and 'So this is it, we're going to die.'
