Murphy goes to the dance and having consumed much black stuff decides to review the talent. As it gets to the last dance he plucks up courage and says to a beautiful girl ' what about me and you getting down to something dirty?' She looks him in the eye and stutters ' I'd like to but I have got the painters in.' He looks bemused and says again 'yes but we could have a great time, you know in your big bed, as your folks are away.' She says I can't I told you, you know monthly time. OK' Murphy just doesn't get it and says 'but I really fancy you and I want to make passionate love to you.' 'Listen' she says 'I cannot have sex with you I am on my monthly cycle'. 'Oh' says Murphy 'that all right I'll follow yous home on me Honda 50'
Boom boom.
