Two guys from Wisconsin and one guy from Illinois are all on death row awaiting execution by electric chair. The first Wisconsin guy is strapped to the chair and is asked, "Do you have anything you want to say before we
throw the switch?" And he says, "Yes sir, I just want to say I'm an innocent man." The warden chuckles a bit to himself then nods to the man at the switch. The switch is thrown and . . . absolutely nothing happens. The warden is amazed. "Son, it seems you have been given you a second chance. Maybe you really ARE innocent. We're gonna let you go free."
The second Wisconsin guy is then strapped to the chair. The warden says, "All right, have you got anything to say?" He says, "Yes sir. I admit that I did kill that feller, but it was all in self defense. I never did it in cold blood." The warden chuckles and nods to the man at the switch, who throws it and . . . absolutely nothing happens. "Well I'll be damned," says the warden, "you must be tellin' the truth too! Let 'im go, boys!" And they unstrap him and set him free.
Finally they bring the Illinois guy to the chair and strap him in. The warden says, "Now, do YOU have anything to say?" And the Illinois guy says, "Sure! If you switched that red wire with that green wire over there, this thing would work!"
ZZZZZZAP!!!!!!!
