This hilarious English/Spanish lesson, Gomaespuminglis, comes from Gomaespuma, the Spanish radio comedy duo of Juan Luis Cano and Guillermo Fesser.

While not quite the same thing as The Cartesian Spanish Pronunciation Lesson, Gomaespuminglis comes close to identifying what makes Spanish and English sound different. However, The CSPL ebook is much more precise, and actually simpler.

Enjoy.
