These two guys go camping, and after two weeks, decide they need a break from each other. So they decide to split up for a few days, and meet up back at the campsite.
When they return, the first guy says, "I had the most wonderful time! I hiked for a few miles, and found a beautiful little stream in a valley. There was a little deer, drinking out of the stream.it was wonderful! I spend the whole three days there."
"Well, that's okay," says the second guy, "but check _this_ out. I followed some train tracks, and found a gorgeous girl, tied to the tracks! I untied her, and we had the most amazing sex, for three days, in every imaginable position!"
"Wow!" says the first guy, envious. "Did she give you oral sex?"
"No," says the second guy. "I couldn't find her head."
