Some years back, one of our friends who ran a small haulage company received delivery of his brand new Scania tractor unit and trailer, all sign written up in the companies advertising logos. Everyone stood in the yard and admired the new rig and the owner's son said he would like to take it out for a run.
After about an hour, anxious Dad received a phone call from his son who told him he had broken the near side rear view mirror. Dad, not very pleased, shouted down the phone, "How the hell did you do that", to which he received the reply, "I rolled the lorry onto it's side".
