A PALM SPRINGS man's confessed canine carnal capers has given cops paws. Joel Bradley Simpson, 36, pleaded guilty to child porn and bestiality charges and will now spend the next 16 months in the pound. He also pleaded guilty to possession of a controlled substance--our old favorite, crystal meth. Simpson, AKA "Hound Dog" got 213 days on the dope beef. He was arrested last June after a snitch fingered him to cops on a kiddie porn beef. But wait, that's not all. A search warrant turned up some home movies starring Simpson and man's really best friend. Joel was seen in the vids performing sex acts with the dog.
