'you ugly stinkin' skunk *beep*
The dubbed version of this movie has some of the most hilarious (and shocking) cursing I have heard in a classic kung fu movie. I can't imagine that it's in the original script... I bet it's the dubbers just having a little fun but it made the movie even more entertaining IMO.
Here it is, if you haven't seen the movie before. Skip to about 2:10
