Upon entering the kitchen, he was confronted by the largest german shepard he had ever seen. The dog bared his fangs menacingly, forcing the mail man against the wall. The mail man shouted, "Lady, call off you dog before he eats me alive." The only response he got was that same high pitch voice coming from the next room saying, "Come in."
Pressing his body against the wall, he slowly worked his way to the door way leading to the next room. Looking around, he saw the room was empty, except for a parrot in a cage. After the threat from the huge dog, he was becoming quite irate and said to the parrot, "Darn you, don't you know any words besides 'come in' ?"
Without a moments hesitation the parrot responded, Sic him!"
