Woman goes to the doctors

[Fireman on a Storm]

Woman goes to the doctors with bruises on her face. Doc asks what happened. She said 'Everytime my husband comes home drunk he hits me' Doc says 'When he comes home drunk, take a glass of water & swish it around your mouth, but don't swallow it till he's asleep. 2 weeks later she goes back to the Doc and says 'It's brilliant, but how does the water work? He never touches me now' Doc says 'The water does wombles all, it's keeping your mouth shut that does the trick'
