A blonde I know decided to have twelve clones made of herself. When she went to the clinic, she found it was a bleak brick house without any windows. When she asked the clone arranger why there were no windows, she was told that people in glass houses shouldn’t grow clones.

As the clones were growing up, she would never be allowed to take them out for a walk as you’ll never walk a clone.

What disturbed her the most was that every time she would visit them, they all would be yelling at the top of their lungs. When she asked why they yelled so much she was told that this was to be expected as she had ordered a dozen I scream clones.
