What does Paul say to Bitterbuck when he starts to get nervous on the way to the electric chair?

When Paul notices that Bitterbuck is nervous, he tightens the grip on Bitterbuck’s elbow and taps the inside of his arm. Then Paul tells the man that the only thing the witnesses will remember about Bitterbuck is how he goes out. So Paul tells him to give them something good and to show them how Washita does it.
