Walking down canal street
Knock on every door
Goddamn son of a bitch
I couldn't find a whore
I finally found a whore
She was rather thin
Goddamn son of a bitch
I couldn't get it in
I finally got it in
Worked it all about
Goddamn son of a bitch
I couldn't get it out
I finally got it out
It was wet and sore
The moral of this story is
To never fuck a whore
Six weeks later
I went for a piss
Goddamn son of a bitch
She gave me syphilis!
Nine months later
I'd forgotten what I did
Goddamn son of a bitch
She brought me home a kid!
