When I was a kid and mum was as broke as she's ever been, she had this car which I've failed to ever see again anywhere, that used to randomly sound the horn occasionally if she turned left. Naturally, it usually went off at the worst of times, like shopping carparksWired up a friends indicator to their horn so when the globe would flash the horn would sound, watched him leave and drive down the street and as soon as he indicated - *honk-honk-honK* around the corner and down the road. Returned 5 minutes later with a Police car behind him
