A man is driving his car on the motorway when suddenly he sees a police car loom up behind him in his mirror. He immediately puts his foot down, reaching 60 mph, then 90 mph then finally 120 mph! Finally the police car catches up with him and he is forced to pull over.
Officer: “Didn’t you see me in the mirror?”
Driver (sweating): “Yes I did.”
Officer: “So why did you speed up then?”
Driver (looking nervously into the police car): “Well officer, my wife ran off with a policeman a week ago… I thought you were bringing her back!”
