Two brothers go hiking together every weekend. Last weekend the older brother said to the younger brother: "why don't we take different trails this time. At the end of the day we'll meet up and share with each other what we saw." The younger brother agrees and off they go. The older brother follows a ridge line and the younger brother follows a valley.

At the end of the day the meet up. The older brother says "I had a great hike following the mountain ridge, beautiful views and saw a bald eagle. What did you see?" The younger brother says "I followed the valley and came to some railroad tracks and decided to follow them for awhile. After a mile or so I found the the most beautiful girl I've ever seen tied to the tracks. I untied her and we had the best sex I've ever had, it was amazing." The older brother is astonished and can't believe it. He asks "well did she give good head?" The younger brother says "well that's the funny thing about it, I never could find her head."
