La Cucaracha

Today I learned something new. "La Cucaracha" the popular Mexican folk song that we hear on ring tones or car horns was a political limerick that became popular during the Mexican Revolution. It was used to voice complaints or poke fun at government by adjusting the words and rhymes. For Americans, it parallels to Yankee Doodle. Here's a song sheet of the era I found on WikiPedia.
