Saw this in todays paper;
Man asks supermarket checkout girl for 50 bags. Checkout girl says 'what do you want them for'. He replies 'I am going to kill my wife and cut her into pieces, put them in the bags'. Thinking that he was joking the checkoput girl says' O K'.
An hour later the man comes back and says 'Can I have another bag please'? The girl says 'Why what happened'.
The man says 'The arse fell out off one'.
