It is funny.
But in today's world of PC culture, I think it might make many folks bend over backwards to cut you slack (up to a point).
Even the cops.
Course, it would go better on a Prius than a big Dodge truck.
I got me a big Dodge truck too.

On the other hand, I don't do bumper stickers. (esp
that one)

Now if you start getting all kinds of unsolicited offers (to bend over forwards), you may have to rethink the strategy.
