GERMAN SHEPHERD DOG WEARING A KIPPAH

The retiring postman went with the new guy on his first day. Now in this street: No17 knock 3 times and push the letters under the door. No 32 knock 6 times and push the letters through the letter flap. No 51 the dog is mean, throw a steak up the hall get in deliver the letters and get out quick. No 17 and 32 no problem. No 51 the rookie says I have this juicy pork chop that I was going to have for lunch for him. He throws the pork chop in goes through the door, a lot of screaming and the rookie comes out clothes torn and bloodied. Who knew a Jewish dog.
