Bob was out in his back garden one day, trying to fly a kite.
He threw the kite up into the air, to see the wind catch it for just a few seconds, before it came crashing back down to the ground.
Bob tried this a number of times, but no matter how hard he tried, every time it was the same result, the kite would stay up for a few seconds and then come crashing down again.
While he was doing this, his wife was watching out of the kitchen window, muttering to herself how men need to be told how to do everything.
She opened up the kitchen window and yelled out to her husband, “You need a piece of tail”.
Bob turned to her with a confused look on his face and said “Make up your mind woman! Last night you told me to go fly a kite!”
