Sesame Street - Small v...vavoom!
The standard English-language version of this animated skit about the lowercase letter "v" is readily available on YouTube. However, throughout the '80s and possibly early '90s, it was seen with a Spanish voiceover announcing the letter as "Ve minúscula." Other needed changes are replacing the English words that appear in the animation ("Voz" for "voice," and an accented "violin"). The Spanish version has yet to turn up online.
