The mail carrier had a registered letter that needed a signature. Receiving no response at the front door, he went around to the back door and knocked.
A high pitched voice from inside said, "Come in." Upon entering the kitchen, he was confronted by a large ferocious German shepherd. The dog bared his fangs menacingly, forcing the mail man against the wall.
The mail man shouted, "Lady, call off your dog before he eats me alive." That same high pitched voice came from the next room saying, "Come in."
Pressing his body against the wall, he slowly worked his way to the next room. It was empty, except for a parrot in a cage.
After being terrified by the huge dog, the mail carrier was furious and said to the parrot, "Darn you, don't you know any words besides 'come in' ?"
Without hesitation the parrot said, "Seize him!"
