(Tasteless joke alert)
A bloke walks into the bar and his friend shouts out to him
"Where ya been all day?"
"Ah, this morning I was walking through the train yard when I came across a woman tied to the tracks."
"Bloody hell!"
"Yeah, I untied her and we've been having sex all day. But I'm so tired now that I thought I'd come in for a pint."
"Geez... You lucky bastard... Did she give you head?"
"No... I looked everywhere but couldn't find it."
