Need a Push A man and his wife are awoken at 3 o'clock in the morning by a knock on the door. The man gets up and goes to the door where a stranger is asking for a push. "Not a chance" says the husband -- "It's three o'clock in the morning!" He closes the door and returns to bed. "Who was it?" asks his wife. "Just a stranger asking for a push" he answers. "Did you help him? she asks. "No I didn't -- it's three in the morning" "Well you've got a short memory" says his wife, "Can't you remember about three months ago when we broke down on holiday and those two guys helped us?. I think you should help him." The man does as he is told and returns to the front door and calls out into the dark "Hello -- are you still there?" "Yes", comes the answer. "Do you still want a push?" calls out the husband. "Yes please!" comes the reply from the dark. "Where are you?" asks the husband "Over here on the swing" the man replies.
