This song is sung to the tune of the Mexican folksong, "Cielito Lindo"

"I am the ruptured cowboy!
"I got the gonorrhea!
"Aye, yah!

"I got it from Maria!
"She gave it to me free-ahh!
"It hurts me when I pee-ahh!
"Aye, yah, yah, yah!"

"aye, yah!" is that untranslatable Mexican expression of joy heard in the
background of Mexican folksongs.

Imagine yourself in a group of roving mariachis at a fiesta as you work on
your rendition of THE RUPTURED COWBOY. You'll win the respect and
admiration of
your associates and co-workers at the next office party.
