The judges humor George, because he "PLAYS" the part. The judges make note that he is "master of illusion" and not the best dancer, just looks the part & gets people into what he's doing.The dance switchup, I would venture a guess, is because George physically could not handle the Jive. In previous shows, George's numerous physical ailments were made known and he's not exactly a spring chicken, so for safety reasons I think it was nice that they allowed him to do the Tango (more suited for him). Besides, it looked like the switch really helped Lisa out, too. She probably would have done poorly at the Tango, yet did well with the Jive.
