Blonde Needed some money

There was a blonde who wanted to make some money, so she decided to kidnap a child and hold him for ransom. She went to the park and grabbed a boy and pulled him behind a tree. She wrote a note that said:

I've kidnapped your son! Leave a bag of 10,000 dollars next to this tree tomorrow at 3 pm.
-Signed: A Blonde.

Then she pinned the note to the kid's shirt and sent him home to show his mom. She went back the next day and sure enough, there was a bag. She looked in the bag and found 10,000 dollars along with a note that said:

Here's your money, but how could you do this to a fellow blonde?
