Three women go to Mexico to celebrate their college graduation.
They get drunk, and wake up in jail, only to discover that they are to be executed in the morning, though none of them can remember what they did the night before.
The first one, a redhead, is strapped in the electric chair and is asked if she has any last words.
She says: "I just graduated from Trinity Bible College and believe in the almighty power of God to intervene on the behalf of the innocent.."
They throw the switch and nothing happens.
They all immediately fall to the floor on their knees, beg for forgiveness and release her.
The second one, a brunette, is strapped in and gives her last words. "I just graduated from the University of Illinois School of Law, and I believe in the power of Justice to intervene on the behalf of the innocent."
They throw the switch and again, nothing happens. Again, they all immediately fall to their knees, beg for forgiveness, and release her.
The last one, a blonde (you knew it), is strapped in and says: "Well, I'm from Ohio and just graduated from Ohio State University with a degree in Electrical Engineering, and I'll tell ya right now, y'all ain't gonna electrocute nobody if you don't plug this thing in."
