Two girlfriends having a cuppa. 'It will rain tomorrow,' the first announces, sipping her tea. 'How do you know?' the other asks. 'I look at my fella's willy', she replies. 'If it's pointing down, it's going to rain. If it's pointing left, it will be cloudy. And if it's pointing right -sunny.' 'So what if it's pointing straight up?' her friend asks. 'In that case,' the first girl laughs, 'who cares about the weather?'
