A man is working in the garden while his wife is in the bathroom getting undressed. But he can't find the rake, so he yells up: 'Where's the rake, sweetheart?' His wife can't hear him. So the man points to his knee and makes a raking motion. His wife still can't work out what he means. So the man repeats the gestures, saying out loud: 'Eye - need - the rake.'
His wife then signals her reply. First she points to her eye, then to her left breast, then to her backside and finally to her groin.
Now the man doesn't understand. Frustrated, he heads up to the bathroom.
'What were you saying?' he asks. 'It's obvious,' his wife replies. 'Eye - left 'it- behind - the bush.'
