Remember in the movie Terminator when the terminator is sitting in the sleazy motel room and the janitor knocks on the door and asks if something died in there? The terminator then ran through an internal list of possible answers for him.
Well 'ol KillerBee kinda has the same function too. Here's some possible answers for the muleyaks that find it neccissary to expose their obvious lack of basic english and tarter ridden teeth to me on occassion...
Response 1. "Your powers of observation are astonishing!.. you must be legendary among your people"
Response 2. "In other news, a new poll shows that indiscriminate a$$holes are making a comeback"
Response 3. (non-verbal) Lean over as if to look around the dirt sack that has spoken to you and take a peek at his/her vehicle. Then slowly turn back around completely ignoring them and go back to whatever activity they interrupted.
Response 4. "You know.. you're absolutely right" Then start sobbing and reach out to them as if you need a big hug. If they're foolish enough to stick around at this point, grab ahold of them and blow your shnoz all over their overalls.
You can start here and practice some of these methods.
