Woman goes to the doctor worried about her husband's temper.
Doctor asks, "What seems to be the problem?"
The woman replies, "I dont know what it is, but every day he just seems to lose his temper for no reason and it scares me."
Doctor says, "I have a simple trick which will cure that."
"Every time it looks like he is about to get angry take a glass of water and sip from it. Dont swallow it just swish it around in your mouth until he calms down or leaves the room."
Two weeks later the woman returns looking fresh and reborn and smiling.
She says, "Doctor, what a brilliant suggestion. Every time my husband started losing it I took the sip of water, swished and swished until he calmed down." Now, how does the glass of water manage that?"
Doctor replies, "The water, itself, does nothing. It the keeping your fecking mouth shut which does the trick!"
