This one may qualify as the worst ever-

Bright rumba:
In the land of senoritas,
Sweet Lolitas and Chiquitas,
There they do a dance as neat as-
Any dance at any ball.

Chorus
La Cucaracha! La Cucaracha!
It's a lively latin dance
La Cucaracha, La Cucaracha!
It's the rumba of romance.
You may have danced to a thousand rumbas,
Old or new, they still recall La cucaracha.
La Cucaracha! It's the daddy of them all.
