A great goofy song is "A Horse Named Bill," sung to the first half of the verse of "Dixie," the part with the words.
"I wish I was in the land of cotton, .
Old times there are not forgotten,.
Look away, look away, look away Dixieland.
.
It's in the database, but I learned it with slightly different words and a couple of additional verses.
A HORSE NAMED BILL
I got a horse and his name is Bill
And when he runs he can't stand still;
He ran away...one day...and also I ran with him.
He ran so fast that he couild not stop.
He ran 'til he came to a barber shop
And fell exhaustionized...with his eye teeth...in the barber's left shoulder.
(then the verses missing from the database)
I got a gal and her name is Daisy;
When she sings the cat goes crazy
With Saint Vituses...and deliriums...and all kinds of cat...uhleptics.
One day she sang a song about
A man who turned himself inside-out
And fell...into the river...because he was so sleepy.
(back to slightly different verses from those in the DB)
I'm goin' out in the woods next year,
I'll shoot for beer and not for deer;
I am...I was..I'll be a great sharpshootress.
At shooting birds I am a beaut;
There is no bird I cannot shoot
In the eyes...in the ears...in the teeth or in the finners.(sic)
In Frisco Bay there lives a whale
And he eats pork chops by the bale,
By the hog's head...by the schooner...and sometimes by the pillbox.
His name is Georgia, he's a peach
But don't leave food within his reach,
Or babies...or nursemaids...or chocolate ice cream sundaes.
He loves to laugh and when he smiles
You see teeth for miles and miles (and miles and miles and miles...)
And tonsils...and spareribs...and things too fierce to mention.
He's lots of fun and when he plays
He rolls his eyes for days and days
And vibrates...and yodels...and breaks the ten commandments.
Oh what can you do in a case like that
Oh what can you do but jump on your hat
Or on an eggshell...or your toothbrush...or on anything else that's helpless
Carl Sandburg included it in his American Songbag.
