Had a couple, and they are good dogs. One we bought that was supposed to be a good squirrel dog, but if you shot a rifle he'd run half a mile. He loved my uncle. Every time he stopped moving the dog would start humping his leg. Dog was good for a laugh if nothing else.
TFF I has a German shepherd female that would jump up in the arm of the chair to hump my goofy nephews head he was like 16 or so at the time. Funniest and strangest thing I've ever seen!
