My favorite part was when they tested and found a Mitchell horse had been tranquilized, they disqualified it and placed it last. Mitchell's excuse (and it may be legit) was that some groom tranquilized the wrong "nutty" horse.

Now if you are accusing a trainer of tranquilizing a horse then I assume that you are saying that the trainer did so to ensure that it would run poorly. Given that, disqualifying it from 4th and placing it last does not seem like much of a penalty to me. Of course, it may just be me...
