This one comes from paTRICK heSTER of P.U.N.Y.

There once was this veterinarian (not to be confused with Heinrich Himmler, a veteran Aryan) who couldn’t afford a proper waste disposal system, and used a regular kitchen trash can to get rid of specimens, an unsanitary practice forbidden by law. One day a customer refused to get his animal vaccinated for rabies and the vet reported him to the local authorities. As a payback, the dog’s owner reported the veterinarian to the Federal Animal Doctor Regulatory Commission (whatever). As a result both men were taken into custody. This proves, of course, that nobody likes a stool pitch in.
