Dr. Duff Poem

My wife, Marilyn, is going through some of her old papers from college tonight and she found this little treasure that I just had to share with the Internet. She wrote this while in a boring sociology class taught by Dr. Duff. Here it is in it's glorious entirety.

Duff, Duff,
I've had enough
Sitting through this class is very rough
You are so boring
I am almost snoring
Where in the world do you get this stuff?
Does it come from your brain?
NO, you are insane.
Does it come from a book?
No, not last time I had a look.
I know where it comes from, you big mass of gas,
The stuff coming out of your mouth originated in your ass!
