La cucaracha, la cucaracha,
ya no puede caminar
porque no tiene, porque le falta
marihuana que fumar.
The cockroach, the cockroach,
can't walk anymore
because it's lacking, because it doesn't have
marijuana to smoke.
Wait a minute...my mother was a Spanish major in college so she knew a number of Spanish language songs. I remember her singing this to me when I was a little girl. She definitely did not sing the marijuana line!
Her favorite song was Cielito Lindo. Here's a version with her favorite Luciano Pavarotti.
Ai ai ai ai.
