Oh Mad Eye, you are a one. You know full well he did not use the bushes for a wee wee. The poor man was stuck in traffic on the motorway and so decided to drive along the hard shoulder until he came to the slip road where he turned off. The police went to interview him about the offence but the fine upstanding citizen that he is told the officers that he had a 'bowel problem' this meant he had to use the lavatory an awful lot. The wily cops did not believe him and so he produced another fine upstanding member of society, a medical doctor, a Manchester Yoonitid medical doctor which is even finer and more upstanding and you just know that he wouldn't lie. This wonderful doctor then signed a statement backing up his boss, ergh patient saying he was treating him for the said medical condition and so he got off, ergh I mean the police realised that he had not done anything wrong at all.
The End.
