Animal jokes-Big bad wolf

Little Red Riding Hood is skipping down the road when she sees a big, bad wolf crouched down behind a log.
"My, what big eyes you have, Mr. Wolf."
The wolf jumps up and runs away.
Further down the road Little Red Riding Hood sees the wolf again and this time he is crouched behind a bush.
"My what big ears you have, Mr. Wolf."
Again the wolf jumps up and runs away.
About two miles down the road Little Red Riding Hood sees the wolf again and this time he is crouched down behind a rock.
"My what big teeth you have Mr. Wolf."
With that the wolf jumps up and screams,
"Will you knock it off, I'm trying to answer nature's call!"
