Bill and Al in Nashville

One day when Bill Clinton and Al Gore were in Nashville, Al took Bill on a tour of his farm east of there. After a tour of the barn, they walked around behind it and discovered a sheep with it's head stuck in the fence. As Bill watched the ewe struggle, he dropped his pants, fell to his knees and mounted the sheep. When he finished he turned to Al and said, "Why don't you try some of that?" Al said, "Ok!" and dropped his pants, fell to his knees and stuck his head in the fence.
