Come along boys and I'll tell you a tale
of my troubles on the old Chisolm Trail

                (Chorus)
Come and Tie my pecker to a tree to a tree come and tie my pecker to a tree..

Well,I rode into town flipping a dime
Saw a pair of panties hanging on a line

             (Chorus)

Walked up the steps Knocked on the door
The gal that answered was a dirty old whore

            (Chorus)

Gave her a dollar to see her cunt
God almighty how the old thing stunk.

            (Chorus)

Her tits hung down like old wooden buckets
Her cunt stunk so that I thought I wouldn't fuck it.

            (Chorus)

I Raised up her dress and threw her on the floor
The Wind from her ass blew the cat out the door

                   (Chorus)

Well I jumped for the saddle but the saddle wasn't there
So I drove nine inches in the old gray mare

                  (Chorus)

She gave me the clap and the blue balls too
The clap don't hurt but the blue balls do

                (Chorus)

The last time I seen her, I ain't seen her since
She was sucking off a nigger through a barb wire fence

                (Chorus)

That's a bout as complete as I can remember it...I heard this in 7th grade on an old 8 track tape with no label accompanied by a dozen more "dirty" songs...would love to get my hands on it again...but I don't even know who the singer was..
It had Roll me over in the clover...lay me down and do it again which would tell dirty limericks in between the chorus...
