A guy was on trial for murder and if convicted, would get the electric chair. His brother found out that a redneck was on the jury and figured he would be the one to bribe. He told the redneck that he would be paid $10,000 if he could convince the rest of the jury to reduce the charge to manslaughter.
The jury was out an entire week and returned with a verdict of manslaughter.
After the trial, the brother went to the redneck's home, told him what a great job he had done and paid him the $10,000.
The redneck replied that it wasn't easy to convince the rest of the jury to change the charge to manslaughter. They all wanted to let him go.
