There's a brunette, red-head, and a blonde all on death row. The day before their execution they are each delivered a message from the judge stating:
"Since you have been on good behavior I will allow you to choose how you will die -- lethal injection or electric chair."
The brunette went first. She chose the electric chair, and it malfunctioned so she was set free.
The red head saw this and picked the electric chair too. It malfunctioned again and she was let free.
Then it was the blonde's turn and when asked what she chose she said, "Lethal injection because the electric chair is broken!"
