Jerks? What is a jerk?
True story. Two members of the Aero Club of Southern Tasmania have fueled up at Devonport prior to crossing Bass Strait to Victoria.
They are putting on their life-jackets. One says to the other, while showing him the red toggle. .. . "Bill , if it comes to it, you will have give this a tug, okay?" "WTF do you mean by that ? " "Well it says it here on this label - JERK TO INFLATE."
(Tasmania is not only home to a hundred appalling incest 'jokes'.)
