I'm not sure which specific story you're referring to about a man testing a taser. There could be many such stories. It might be about a police officer training with a taser, or a civilian who got hold of one for self - defense and decided to test it in a safe environment. Without more context, it's hard to say exactly what the story is.
He could have bought it because they live in a place where crime is common. He wants his wife to be able to defend herself when he's not around. It's a way of showing his care for her safety.
At a self - defense class, the instructor was showing how to use a taser. One over - eager student grabbed it the wrong way and when he tried to activate it, it just made a strange buzzing sound. He looked so confused as if the taser was playing a trick on him. The whole class couldn't help but chuckle at his bewildered expression.
Here's one. A husband was imitating a zombie and chased his wife around the yard. His wife grabbed a taser (a fake one from a Halloween prop) and when he got close, she pointed it at him. He stopped immediately and started doing a silly dance instead. It was really funny to see him change from a 'zombie' to a dancing fool so quickly.
There was this couple. The husband loved to play pranks on his wife. One day, he hid all of her favorite shoes. When she found out, she chased him around the house with a taser (it was a toy one actually). The husband was running and screaming like he was in a horror movie. Eventually, he gave up the shoes' hiding place and they both ended up laughing about it.
Well, there was this time at a self - defense class. The instructor was demonstrating a taser. He aimed at a dummy but misjudged the distance a bit. Instead of just hitting the dummy, the taser wire got tangled around a nearby chair, making the chair jerk around in a really comical way.
Well, once I accidentally tasered myself while showing it to a friend. I thought the safety was on but nope. It was a jolt that made me jump like a crazy kangaroo. My friend couldn't stop laughing for minutes.
Well, if it's a real - life scenario, perhaps the man with the taser was a security guard. He might have used the taser to subdue a suspect who was causing trouble in a building or at an event. The taser would have been used as a non - lethal means to stop the person from endangering others. However, without more context, it's hard to say exactly what the story is.
