Attractive lady to electrician:
'Can you help me I've got a screw loose?'
'You need a psychiatrist for that, my love.'
'I just want you to tighten up my screw!'
'We don't do small jobs like that.'
'But it's a big screw.'
'I tell you what. I have a much better screw here. I will put it in for you, turn it nice and tight and won't charge you a penny!'
