Officer Roland, near the end of his shift, noticed a woman driving a small pickup truck with a dog sitting on her lap.  Observing that this was an unsafe manner in which to be operating her vehicle, he pulled her over.

After exiting his cruiser and approaching the woman's driver side window, the lady asked, "Why officer what on earth did you pull me over for?"

Officer: "I pulled you over because it isn't safe to drive with a dog on your lap."

Lady: "Why officer, it is exactly for safety that I have the dog on my lap. You see my truck is an older model and isn't equipped with an air bag.  But that's OK now because this is a special kind of dog just for that purpose!"

Officer: "Just what makes you think its OK to use that dog like an air bag?"

Lady: "Well the man at the pet store did tell me it was a dash-hound."
