Original Joke I thought of.

This is a joke I thought of and wondered how long it will be before I hear it, either told me or on the TV.

I was driving on the motorway, with my wife in the passenger seat and my brother in the back seat.

I was overtaken by a woman driver who cut in rather sharp then immediately did an emergency stop. I braked as hard as possible, blew my horn and shouted out "You OLD WITCH !"

As I said it, my phone burst into life and seconds later my wifes phone started ringing. (Voice activation at its worst)

My wife asked with a scowl  "How come your phone has called me ?"

Oh! Thats must have been when I blew the horn, I must have pressed  Number One on my speed dial on my steering wheel, because you are my number one!" I lie convincingly.

My wife sighs and says " Oh MY LOVER you are so sweet."

Suddenly her phone bursts into life and then my brothers phone starts ringing.

I wonder why?
