Ever watch "Snakes On A Plane" on regular tv? Talk about ridiculous language "clean-up." "I've had it with these monkey fighting snakes on a plane." Seriously, in some cases I'd rather they just silence the words than add all the senseless dribble/drabble.
I did a search on "edited for tv" scenes and found this. Take a look. You'll find some of it is hilarious. (Check out the Exorcist for instance)
