I often get asked: "do people from one spanish-speaking country understand people from another?" (spanish-speaking country)
The question could sound naive, but is actually justified considering that, for example, in the "german speaking area" alone you have so many different languages and dialects. I can attest to the fact that a northern and southern german can not understand each other if each of them speaks in their own dialect (similar for swiss-german, or austrian-dialects, etc.)
So usually I answer with "Of course! There are just some subtle differences to take into account, some different expressions, words, pronunciations, that's all.... little details. We understand each other just fine!".
Well... these guys here beg to differ big time!!!
And they do so in a most funny, brilliant, talented and creative way!
(If you speak spanish... enjoy! If you don't... hope you can read the subtitles fast enough, but better yet... learn spanish... or maybe don't ;-)
