Railroad...........

[Shaglene]

A man is telling his friend of a recent experience: "I was walking along beside the railway line" he says, "When I saw this girl tied to the tracks. Well, naturally I freed her, pulled her off the tracks and ended up having sex with her all night."
"Did you get a b*** job?" asks his friend.
"No!" he says, "I never did find the head."
