Three women go down to Mexico one night to celebrate college graduation.
They get drunk and wake up in jail only to find that they are to be executed in the morning, though none of them can remember what they did the night before.
The brunette, is strapped in the electric chair and is asked if she has any last words.
She says, "I just graduated from Brigham Young University and believe in the almighty power of God to intervene on the behalf of the innocent."
They throw the switch and nothing happens.
The Mexicans immediately fall to the floor on their knees; beg for her forgiveness and release her.
The second woman, a redhead, is strapped in and gives her last words: "I recently graduated from the Harvard School of Law and I believe in the power of justice to intervene on the part of the innocent."
They throw the switch and again, nothing happens.
Again, they all immediately fall to their knees; beg for her forgiveness and release her.

The last woman, a blonde, is strapped in and says, "Well, I'm from the University of Kentucky and just graduated with a degree in Electrical Engineering and I'll tell ya right now... y'all ain't gonna electrocute nobody if ya'll don't plug this thing in."
