A blonde kidnapped a little boy and brought him to her apartment. Her ransom note said, "I've kidnapped your son. Please leave a ransom of $5,000 under the bench by the tennis courts in the park."
Then she pinned the note to the back of the boy's shirt and sent him home.
She went to the park the next day and, sure enough, $5,000 was in a basket under that bench. With it was a note from the mother of the boy: "How could you do this to a fellow blonde?"
