There was originally a line in one of the first trailors 'I've had it with these snakes', which was widely seen as more or less what /would/ be the appropriate place for '(get/I want) these motherfucking snakes off (my/this) motherfucking plane)'.  While it is widely belived (and openly hinted at by the production team), i've never seen any report of where/how this line has made it into the final production.
