I followed Cool Bean's link to "Billy's Mule, and then found this on down that page; I haven't actually heard this, but the lyric has to be a real contenduh:

TITLE: The Prince's Panties
Lyrics and Chords

[Capo 2]

There was once a prince who acted strangely in that
He thought life was stupid and it was for him so
He made up a world in which he liked the things we liked
But he had different reasons why he liked them

/ D - / C - / D - / C - /

He liked butter for its color
He would order toast and color
Waitresses, confused would utter
Sir, I've never heard of toast and color

He'd get angry and begin to choke them
The law would come, and they'd arrest and book him
So his life was a mess of trouble
Still he kept it up

/ " / " / Bb - / A - /

He had dogs, a hundred cocker spaniels and he
Called them panties, 'cause they did that mostly, and he
Did not care at all if they would bark and fetch sticks
Run and jump, roll over, and play dead tricks

No, he liked them only for their panting
So he would run them ragged, but one day they got fed up
And chased the prince right up against the fence
And the prince was eaten by his panties

... / Bb - / A D B - /
