I have a dog, I have a dog
that jumps about and leaps like a frog.
I have a dog, Yes, a pure black dog
who leaves behind brown turd logs.
I have a dog, a big black bitch
in hygiene and wits she's really not rich.
I have a dog, who doesn't know her name
who's known for being helplessly lame
To own her is a curse and a terrible shame
But she is my dog and in my care of course
so I must majestically attend her by sheer force.

Rafael Cazares
