A man received this message from his neighbour... "Sorry sir I am using your wife...I am using day and night ...I am using when u r not present at home ... In fact I am using more than u r using...I confess this because now I feel very much guilty... Hope u will accept my sincere apologies." The man shot his wife !!! A few minutes later he received another message: "Sorry sir spelling mistake... It' s not wife.. but wifi."
